Application
WPBC Pushbutton Stations
are designed for all heavy-duty
applications (i.e., crane or
mill-type drives) that require
the combination of single and
multi-speed performance and
where conditions require a
NEMA 3R rainproof enclosure
for outdoor service.
WPBC stations can also be
supplied in NEMA 13 enclo-
sures for oil-tight and dust-tight
indoor service.
For watertight and dust-tight, in-
door and outdoor service, the
NEMA 4 enclosure is avail-
able. This enclosure has a
drain plug on the bottom and
a space heater inside the
enclosure to minimize
moisture buildup.
Description
The front, back and end plates
of the WPBC pushbutton enclo-
sures are machined of extruded
aluminum. The removable side
covers are machined aluminum
extrusions with neoprene gas-
kets to insure a tight seal.
Large, flexible, neoprene boots
cover the operating plungers.
This boot has flanges which
engage machined channels
and make a leakproof seal
with the top plate. Options
available include: A pilot light
to signal when power is on, a
circuit-disconnect toggle switch,
reset button and maintained
contact inserts. Other options
are available to meet your
special needs.
All WPBC stations are supplied
with a grounding connection.
