Section 2—General Characteristics

Tropicalization

Compact NS circuit breakers comply with NF C 63-100 standard level 2 conditions (95% relative

humidity at 45° C or 80% at 55° C, hot and humid climate conditions). The materials used in Compact

NS circuit breakers will not support the growth of fungus or mold.

They also comply with the following standards:

•

IEC 68-2-30 damp heat

IEC 68-2-2 dry heat

IEC 68-2-11 salt spray

IEC 68-2-1 low temperatures

Pollution Degree

Compact NS circuit breakers are certified for operation in pollution degree III environments as defined

by IEC standard 947 (industrial environments).

Environmental

Protection

Compact NS circuit breakers take into account concerns for environmental protection. Most

components are recyclable and parts are marked as specified in applicable standards.

Suitability for

Isolation (Positive

Contact Indication)

All Compact NS circuit breakers and switches are suitable for isolation as defined in the IEC 947-2

Standard:

•

The isolation position corresponds to the O (OFF position).

The operating handle cannot indicate the OFF position unless the contacts are open.

Padlocks may not be installed unless the contacts are open

Installation of a rotary handle or a motor mechanism does not alter the functionality of the position

indication system.

The isolation function is certified by tests guaranteeing:

•

The mechanical reliability of the position indication system

The absence of leakage currents

Overvoltage withstand capacity between upstream and downstream connections

Circuit Breaker Marking

Switch Marking

Installation in

Class II

Switchboards

All Compact NS circuit breakers, even when fitted with a rotary handle or a motor mechanism, can be

installed through the door of Class II IEC switchboards (as per IEC 664 Standard). Refer to circuit

breaker installation instructions prior to installing circuit breaker.

Installation requires no special insulation because Compact NS circuit breakers provide Class II

insulation between the front face and all internal circuits.

Current

Limited

Isc

tsc

The exceptional limiting capacity of the Compact NS line is due to the double break technique (rapid

natural repulsion of contacts and the appearance of two arc voltages in series with a steep wavefront).

The limiting capacity of the Compact NS line greatly reduces the forces created by fault currents in

devices. The result is a major increase in breaking performance. In particular, the service breaking

capacity Ics is equal to 100% of Icu.

The Ics value, defined by IEC 947-2, is guaranteed by tests comprising the following operations:

•

Breaking a fault current equal to 100% of Icu three times consecutively

Checking that the device continues to function normally

Conduction of rated current without abnormal temperature rise

Protection functions perform within the limits specified by the standard

Suitability for isolation is not impaired

Longer Service

Life of Electrical

Installations

Current limiting circuit breakers greatly reduce the negative effects of short circuits on installations.

Thermal Effects

Less temperature rise in conductors, therefore longer service life for cables.

Mechanical Effects

Reduced electrodynamic forces, therefore less risk of electrical contacts or busbars being distorted or

broken.

Electromagnetic

Effects

Less disturbance for measuring devices located near electrical circuits.

Setting Example

Question: What is the overload protection threshold of a Compact NSJ400 circuit breaker equipped

with trip unit STR23SP where Io = 0.5 and Ir = 0.8?

Answer: In x Io x Ir = 400 x 0.5 x 0.8 = 160 A

The same trip unit with the same settings, mounted on an NSJ600 circuit breaker will have the following

tripping threshold: In x Io x Ir = 600 x 0.5 x 0.8 = 240 A.

•

LED (9) lights solid when current exceeds 0.9 Ir

LED (9) flashes when current exceeds long-time threshold Ir

Fault Indications

LEDs indicate the type of fault that caused tripping:

•

Overload (LT protection) or abnormal component temperature (>Ir)

Short-circuit (ST or instantaneous protection) (>Isd)

Ground-fault (if earth-fault protection option is present) (>Ig)

Microprocessor malfunction—both (>Ir) and (>Isd) LEDs go on, plus the (>Ig) LED, if the ground-

fault protection option is present

The LEDs are battery powered with spare batteries supplied in the adapter box. When a fault occurs,

the LED indicating type of fault shuts off after approximately 10 minutes to conserve battery power. The

fault data is stored in memory and the LED can be re-illuminated by pressing the battery/LED test

button (9). The LED automatically goes off and memory is cleared when the circuit breaker is reset.

A digital display continuously indicates the current of the phase with the greatest load. By pressing a

scroll button, it is also possible to display successively the readings of I1, I2, I3 and I neutral. LEDs

indicate the phase for which the current is displayed.

Zone-selective

Interlocking (ZSI)

A number of circuit breakers are interconnected one after another by a pilot wire. In the event of a

short-time or earth fault:

•

If a given trip unit STR53UP detects the fault, it informs the upstream circuit breaker which applies

the set time delay

If the trip unit STR53UP does not detect the fault, the upstream circuit breaker trips after its shortest

time delay

In this way, the fault is cleared rapidly by the nearest circuit breaker. In addition, thermal stresses on

the circuits are minimized and time discrimination is maintained throughout the installation.

Opto-electronic

The use of opto-transistors ensures total isolation between the internal circuits of the trip unit and the

to protect only the molded case switch itself. Magnetic settings:

•

NSF150/250 A switches: 2000 A

NSJ 400/600 A switches: 6000 A

These switches are suitable for use on a circuit capable of delivering not more than:

•

240 V: 100 kA for NSF switches and 150 kA for NSJ switches

480 V: 65 kA for NSF switches and 100 kA for NSJ switches

600 V (600Y/347 for NSF switches): 25 kA

Switches are Listed under UL file E103740 and Certified under CSA file LR 88980.

Auxiliary switches provide remote information of the circuit breaker status and can thus be used for

indications, electrical locking, relays, etc.

Functions

•

OF (open/closed): auxiliary switch—indicates position of the circuit breaker contacts

SD (trip indication): bell alarm—indicates that the circuit breaker has tripped due to

— Overload

— Short circuit

— Ground fault

— The operation of a shunt trip or undervoltage trip or the "push-to-trip" button which resets when

the circuit breaker is reset

•

Operation of a plug-in base or chassis when attempting to withdraw the circuit breaker in ON

position; SDE (fault indication): indicates the circuit breaker has tripped due to an overload, short

circuit or ground fault; resets when circuit breaker is reset

CAM (early-make or early-break function): indicates the position of the rotary handle; used in

particular for advanced-opening safety trip devices

•

Connected/disconnected: indicates the position of a drawout circuit breaker

Switching of very low loads: all above auxiliary switches are also available in low-level versions

capable of switching very low loads (e.g., for controlling PLCs or electronic circuits)

Standards

Installation

Auxiliary switches comply with UL 489, CSA C22.2 No. 5.1 and IEC 947-5 Standards. “Low-level"

switches are not UL Listed.

•

Functions OF, SD and SDE:

— Switches snap into cavities under front accessory cover of the circuit breaker

— For Compact NSF150–NSJ600 circuit breakers, one model serves for all indication functions

depending on where it is fitted in the circuit breaker

•

SDE function of a circuit breaker equipped with a thermal-magnetic trip unit requires the SDE

actuator

CAM: to be fitted in the rotary handle module; depending on how it is installed, it ensures either the

SHUNT TRIP AND UNDERVOLTAGE TRIP

A voltage release can be used to trip the circuit breaker via a control signal.

Undervoltage trip

(MN)

•

Trips circuit breaker when the control voltage drops below a tripping threshold

Drops out between 35% and 70% of rated voltage

Circuit breaker closing is possible only if the voltage exceeds 85% of rated voltage

Permanent type

If an overvoltage condition exists, operation of circuit breaker closing mechanism will not permit the

main contacts to touch, even momentarily

Shunt trip (MX)

Operation

•

Trips the circuit breaker when control voltage rises above 70% of its rated voltage

Impulse type ≥ 20 ms or maintained control signals

AC shunt trips can be operated at 55% of their rated voltage, making them suitable for ground-fault

protection when combined with a Class I ground-fault sensing element

•

The circuit breaker must be reset locally after being tripped by shunt trip or undervoltage trip

(MN or MX)

MN or MX tripping has priority over manual (or motor operator) closing; in the presence of a

standing trip order such an action does not result in any closing, even temporarily, of the main

contacts

•

Endurance: 50% of the rated mechanical endurance of the circuit breaker for Compact NSF150–

NSJ600 circuit breakers

Installation and

Connection

Interlocking with

Keys

For circuit breakers equipped with rotary handles or a motor mechanism. Interlocking with keys may be

easily implemented by equipping each of the Compact circuit breakers, either fixed or drawout

mounted, with a directly mounted rotary operating handle and a standard keylock, but with only one key

for the two keylocks. This solution enables interlocking between two circuit breakers that are

geographically distant or that have significantly different characteristics.

Section 13—Supplementary Technical Information

EFFECT OF HIGH TEMPERATURES

When the ambient temperature is greater than 40° C, overload protection characteristics are slightly

modified. When determining tripping times using time/current curves, the Ir values corresponding to the

thermal setting on the circuit breaker must be reduced using the coefficients below:

45° C

50° C

55° C

60° C

65° C

70° C

0.975

0.95

0.925

0.90

0.875

0.85

Example

What is the tripping time for a TM200DP circuit breaker with a 400A fault current and an ambient

temperature of 40° C?

•

Ir = 200 A

I/Ir = 400/200 = 2

On the time/current curve, t = 100 s.

Consider the same conditions, except an ambient temperature of 65° C. What is the tripping time?

•

Ir = 200 x 0.875 = 175 A

I/Ir = 400/175 = 2.28

On the time/current curve, ≈ 65 s.

Section 13—Supplementary Technical Information

REFLEX TRIPPING

All Compact NS circuit breakers and switches incorporate the exclusive reflex tripping system.

This extremely simple system breaks very high fault currents by mechanically tripping the device via a

"piston" actuated directly by the pressure produced in the breaking units resulting from a short circuit.

For high short-circuit thermal withstand, this system provides a faster break. Reflex tripping curves are

exclusively a function of the circuit breaker rating.

Section 13—Supplementary Technical Information

Dielectric

After testing, the circuit breaker must withstand for one minute a voltage of 1000 V plus twice the rated

voltage between:

•

Line and load terminals with circuit breaker in open, tripped and off positions

Terminals of opposite polarity with circuit breaker closed

Live parts and the overall enclosure with circuit breaker open and closed

Optional Tests

•

High available fault current—circuit breakers having passed all the standard tests may have the UL

Listing label applied at higher values than the standard; test sequence is as follows:

— 200% calibration

— Interrupting capacity: an opening operation followed by a close-open operation (O-and-CO) on

all poles are performed on the circuit breaker

The power factor over 20000 A shall be 0.15–0.2 lagging:

— Trip out at 250%

— Dielectric at twice the rated test voltage

•

100% rated—circuit breakers having passed all the standard tests may have the UL Listing label

applied to use the circuit breaker in an enclosure when carrying 100% of its maximum rating

The circuit breaker is submitted to additional temperature tests performed as standard tests, except

that the circuit breaker is installed in an enclosure. The dimensions and possible ventilations shall be

recorded and shall be marked on the circuit breaker.

Tests On

Accessories

Shunt trip and Undervoltage Trip—these devices are submitted to temperature, overvoltage, operation,

endurance and dielectric tests.

Overvoltage Test—the device must be capable of withstanding 110% of its rated voltage continuously

without damage (this test does not apply to a shunt trip with an "a" contact connected in series).

Operation:

Shunt Trip—must operate at 75% of its rated voltage (except shunt trip devices for use with ground-

fault protection shall operate at 55%).

Undervoltage Trip—must trip the circuit breaker when the voltage is less than 35% and may trip the

circuit breaker between 35 and 70% of its rated voltage and shall pick-up and seal when the voltage

is at 85% or more of its rated voltage.

Endurance—the device must be capable of performing successfully for 10% of the number of "with

current" operations of the circuit breaker.

Auxiliary and Alarm Switches—auxiliary and alarm switches must be submitted to temperature,

overload, endurance and dielectric tests.

Overload Test—the test consists of fifty operations making and breaking 150% of rated current at rated

voltage, with a 75–80% power factor in ac and non-inductive load in dc.

Endurance—the switch must make and break its rated current at rated voltage, with a 75–80% power

factor in ac, and non-inductive load in dc for 100% of the number of operations "with current" for

auxiliary switches, and 10% of this number for alarm switches.

Motor Operator—the motor operator shall perform the number of "without current" operations indicated

for the circuit breaker endurance tests. The first 25 operations shall be conducted at 85% of the motor

operator voltage rating. The circuit breaker is to be tripped during these tests. The next 25 operations

shall be conducted at 110% of the motor operator voltage rating. The balance shall be completed at

rated voltage without tripping the circuit breaker.

IEC 947-2 TEST PROCEDURE

Standard Tests

Consisting of seven parts, the IEC 947 Standard applies to all low-voltage equipment designed for

industrial application.

Three documents are to be consulted for circuit breakers and switches:

•

IEC 947-1: general regulations

IEC 947-2: circuit breakers

IEC 947-3: switches

Two Categories of

Devices

The IEC 947-1 standard defines two categories of devices:

•

Category A—devices not specifically designed to carry out chronometric selectivity

Category B—devices specifically designed to carry out chronometric selectivity; these circuit

breakers possess a compulsory additional characteristic: short-time withstand (Icw)

Breaking Capacity

Ultimate Breaking

Capacity: Icu

Icu is the value to be taken into account when calculating an installation. The rule remains: Icu > Icc

(maximum fault current of the installation).

Breaking

Performance During

Operation: Ics

This characteristic indicates the ability of the device to eliminate short-circuit currents less than Icc and

with a greater likelihood of occurring, generally near the application. Ics is expressed in % of Icu (values

retained by the standard IEC 25-50-75-100% of Icu). This test sequence designed to check the Ics

performance, groups together on the same device, following the breaking test (O-CO-CO, see page

72), certain checks such as:

•

Temperature rise under In

Calibration at 1.45 In

Leakage current (for devices suitable for disconnection)

The leakage current should not exceed 2 mA under the application voltage (0.5 mA when new). These

checks ensure that the device is able to carry out all its functions after elimination of a fault of Ics value

and to be put back in operation; hence the notion of breaking power performance during operation Ics.

Section 13—Supplementary Technical Information

Isolation

Function

Recognition and definition of the disconnection capacity for industrial low-voltage equipment:

Until recently, circuit breaker standards have established no regulations concerning the isolation

function. Only the installation standards provided some rather vague information. The IEC 947

standard takes this function into account. In the "general regulations" section, it clearly states:

•

The manufacturing regulation

The tests to be performed

The circuit breaker standard should define the manner in which the tests are to be performed (under

study). The manufacturing regulations state, for example:

•

Both the isolation and the inner contact distances (open > 8 mm)

A device indicating the true position of the contacts (operating handle if representative of the state

of all the contacts)

•

When a "locked" position is provided, this should only be possible with "open" contacts

The tests to be performed are as follow:

•

Shock wave voltage strength (Uimp)

12.3 kV

0.9

Uimp

0.5

0.1

t2 1.2

tμs

1.2/50 μs–12.3 kV plus 25% between open contacts in comparison with devices not fitted with the

applied isolation function according to the figure below. The test is validated if no triggering occurs

between the contacts.

•

Measurement of leakage current—under 110% of the device application voltage, maximum leakage

currents proposed per pole:

— 0.5 mA new device

— 2 mA device after Ics

— 6 mA device after Icu or after endurance tests, representative of the "end of service life."

ROUTINE AND MAINTENANCE GUIDELINES

Recommended

Inspection

Intervals

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.

See NFPA 70E.

• This equipment must only be installed and serviced by qualified electrical personnel.

• Turn off all power supplying this equipment before working on or inside equipment.

• Always use a properly rated voltage sensing device to confirm power is off.

• Replace all devices, doors and covers before turning on power to this equipment.

Failure to follow this instruction will result in Failure to follow these instructions will result

in death or serious injury.

CAUTION

HAZARD OF EQUIPMENT DAMAGE

Molded case circuit breakers contain factory-sealed and calibrated elements. The seal must not be

broken and the circuit breaker must not be tampered with. Molded case circuit breakers should not

be field adjusted or repaired. In the case of a malfunction, the circuit breaker should be replaced or

inspected at the Schneider Electric factory, or by an authorized representative.

Failure to follow this instruction can result in equipment damage.

Merlin Gerin circuit breakers are designed to be maintenance-free. However, all equipment with moving

parts requires periodic inspection to ensure optimum performance and reliability. It is recommended

that the circuit breakers be routinely inspected six months after installation, followed by annual

inspection. Intervals can vary depending on particular usages and environments.

Inspection of

Terminals

•

Connections to circuit breaker terminals should be inspected. If there is discoloration due to

overheating, the connections should be disassembled and the surface cleaned before reinstallation.

It is essential that electrical connections be made carefully in order to prevent overheating.

Check for terminal tightness.

Cleaning

Remove dust and dirt that have accumulated on the circuit breaker surface and terminals.

Mechanical

Checks

Even over long periods of time, circuit breakers are not often required to operate on overload or short-

circuit conditions. Therefore it is essential to operate the circuit breaker periodically. To trip the circuit

breaker, push the push-to-trip button.

Section 13—Supplementary Technical Information

Insulation

Resistance Tests

When a circuit breaker is subjected to severe operating conditions, an insulation resistance test should

be performed as indicated in NEMA standard publication No. AB4-1996. An insulation resistance test is

used to determine the quality of the insulation between phases and phase-to-ground. The resistance

test is made with a dc voltage higher than the rated voltage to determine the actual resistance of the

insulation.

The most common testing method employs a "megger" type instrument. A 1000 V instrument will

provide a more reliable test because it is capable of detecting tracking on insulated surfaces.

Resistance values below one megohm are unsafe and should be investigated. An insulation test should

be made:

•

Between line and load terminals of individual poles with the circuit breaker contacts open

Between adjacent poles and from poles to the metallic supporting structure with the circuit breaker

contacts closed. The latter test may be done with the circuit breaker in place after the line and load

conductors have been removed, or with the circuit breaker bolted to a metallic base which simulates

the in-service mounting.

Electrical Tests

These tests require equipment for conducting pole resistance, overcurrent and instantaneous tripping,

in accordance with NEMA Standard publication No. AB4. They are not within the scope of normal field

operation.
