Application
Euclid PBP Pushbutton Stations
are commonly employed for
control of electrically powered
industrial equipment such as
electric overhead traveling
(EOT) cranes, hoists, electro-
magnets, etc…wherever
safety and reliability are of
greatest concern.
The PBP Pushbutton Stations
are suitable for most industrial
environmental conditions, in-
door and outdoor, within the
following temperature range:
0° to 180°F (–18° to 82°C).
• Electrically insulated,
highly durable weather-
proof nitrile-vinyl rubber
enclosure with a durom-
eter reading exceeding
that of an automobile tire.
The plug-in inserts permit any
unit to be inspected or replaced
without disturbing the originally
installed wiring, hence, mini-
mal down time. The modular
units can be easily arranged in
any order in the pendant station.
The Pushbutton inserts are high
impact and shock resistant and
high dielectric strength molded
phenolic with oversize silver
contacts that operate with a
positive wiping action offering
excellent contact reliability. The
multi-speed inserts have a one
piece self-lubricating ‘’Nylatron”
plunger-cam for easier opera-
tion and greater durability.
Nameplate marking kits are fur-
nished with the enclosure. Spe-
cial markings can also be pro-
vided at an additional cost.
• Molded enclosure, high
visibility safety yellow.
• Ground connection at the
conduit entrance/cable
support area.
Kellems grips are available and
provide positive strain relief for
the multi-conductor cable, in-
creasing its service life many
times, thus avoiding unneces-
sary downtime and mainte-
nance costs. Refer to price
sheet for part numbers and
cord diameters.
• AC and DC rated.
• Choice of 1, 2, 3
or 4 motion enclosures.
• Plug-in single through five
speed inserts for easy in-
stallation, inspection or
replacement without
disturbing wiring.

Compact Pendant Pushbutton

NEMA Type 4X Enclosure
Hubbell’s Compact Pendant
Stations are typically used to
control industrial cranes and
hoists or the remote control
of industrial machines.
• Mechanical interlock on
reversing stations prevents
actuating both pushbuttons
simultaneously.
Application
Industrial plants have
expanded the use of
electric motor driven
hoists (over the chainfall
types) as the need for
• UL and CSA listed.
greater hoist capacity has
increased. These electric
motor hoists are an excel-
lent application for the
Hubbell Compact Pen-
dant. Especially in areas
where the stations are sub-
ject to operational abuse.
This high-quality pendant sta-
tion features a tough molded
polymer housing that meets
the most rigorous requirements
of industrial applications and
their environments for control
of electric hoists. The compact
pendant is rated NEMA 4X
when used with the cord
connector kit.
• Ambient Temperature
Range –20° to 158°F
(–29° to 70°C)
• Optional - Cord Connec-
tor Kit - to permit use in

cations or for out-
Locations include jib cranes
on building columns, small
overhead hoists on gantry
cranes, and even the operation
of hoists applied to single
girder cranes.
door use.
These pendant stations are
designed for the comfort of the
operator in controlling the hoists
and built to withstand hostile
environments in the industrial
arena.
• Safety Yellow high impact
polymer enclosures.
• A compact pendant sta-
tion engineered to fit the
hand comfortably.
Most of the electric hoists have
reversing electrical relays or
contactors which can be con-
trolled from a single control con-
tact and these pendant stations
are designed for those hoist ap-
plications, not for the direct
power handling of the motor
current in the pendant station.
• Choice of single-speed,
two-speed, or on-off
capabilities.
Jogging operation of floor-
mounted machines away from
the main operator’s station is
generally associated with only
one motion, easily handled by
the pendant station applied to
an umbilical cord.
U
These stations have also been
used very successfully for winch
control on recreational vehicles
and tow trucks and for dock
control with carriers in the
food industries.

Euclid™ PBM Pendant Pushbutton Stations
Cord Connector Kits:
The Multi-Purpose PBM Pen-
dant Pushbutton Stations have
been designed to use 22mm
NEMA 4X pushbutton ele-

Spacing of the mounting holes
will permit enlarging the hole
to install the larger 30mm

Hubbell’s maintained pushbuttons are available in two variations. Single button
mushroom head “push/pull” units are stand alone buttons that are commonly used for
a maintained “emergency stop” function which has “push-to-stop/pull-to-start” operation.
Single maintained buttons are used with another operator and an MRI “maintained reset
interlock” to provide two button operation for either “maintained/maintained” or
“maintained/momentary” action.
