Bulletin 2015 Heavy-Duty – Cam-Operated NEMA Type 1 Enclosure
Application
PBC pushbutton stations are
designed for all heavy-duty ap-
plications that require the com-
bination of single and multi-
speed units and operation with
special contact sequencing.
Description
The enclosures front plate and
end cups are die formed from
heavy gauge steel and welded
into an unbreakable unit. The
protective plunger guards are
integral to the front plate. The
double suspension cable
hanger and threaded conduit
fitting are an integral part of the
top cap.
The front plate is designed to
provide a bearing surface for
the pushbutton plungers and a
trough for the control wires.
The U shaped access cover,
which serves as the sides and
back of the enclosure, is
molded of high strength fiber-
glass and is easily removed for
inspection or maintenance of
the pushbutton inserts. Interior
assemblies may be inspected
and contact block assemblies
are easily replaced. Interior as-
semblies consist of overlapping
mounting rib sections to which
the contact blocks are attached.
Each unit is fastened to the front
plate with two screws. This de-
sign permits easy replacement
of individual parts or a com-
plete two button assembly.
Options available with PBC
Pendants include: A pilot light
to signal when power is on, a
circuit-disconnect toggle switch,
reset button and maintained
contacts. Other options are
available, on request, to meet
your special needs.
All PBC stations are supplied
with a grounding connection.
