Applications
• For use in hazardous areas as dened by the National Electrical
Code (NEC), and Canadian Electrical Code (CEC).
• For use in washdown areas and other damp, wet and highly
corrosive areas.
• Push buttons and selector switches are used in conjunction with
contactors or magnetic starters for remote control of motors
in hazardous locations. They provide circuit control and/or
selection.
• Pilot lights provide visual assurance that an electrical function is
being performed at a remote or local hazardous location.
• For installation in:
— Chemical and petrochemical plants
— Reneries
— Pulp and paper processing plants
— Other industrial applications
Features
• Corrosion resistant captive stainless steel screws hold covers
to body.
• Available with two types of explosion proof protection. The
Labyrinth switch is rated A600 heavy pilot duty and P150.
• Durable materials and construction exceeds UL environmental
requirements including impact.
• Enclosures constructed of specially formulated berglass
reinforced thermoset polyester with low surface resistivity that
will not hold a static charge.
• Wide variety of devices and options results in a control station
tailor made to the application.
• Pilot light employs LED cluster with lifetime of 100,000 hours
that can be used at either 120 Vac or 240 Vac.
• Optional pilot light has 12 Vac/24 Vdc ratings.
• Both the standard hub and union hub provide ground path
continuity in feed-thru applications.
• Factory sealed –– no external seals required.
• Optional union hub allows temporary rotation of hub for ease
of installation.
Standard Materials
• Body and cover: berglass reinforced thermoset polyester
• Standard hub, union hub and ground plate: stainless steel and
®
Noryl
• UCPB push button and UCSS selector switch operators:
polyester, Valox™, and stainless steel
• Screws: stainless steel
• Pilot light: glass jewel
Options
• UCPL Pilot Light is red as standard; if green is desired, add
sufx -JGBG; if amber is desired, add sufx -JGBA; if blue is
desired, add sufx -JGBB.
• For Vdc pilot light, add sufx -DC to catalog number (push
buttons and selector switches have Vac and Vdc ratings as
standard).
• Push button front operated mushroom head (maintained
contact): standard color is red. Also available in green, add
sufx -NMRBMGR; and black, add sufx -NMRBMBL.
• Push button front operated mushroom head (momentary
contact): standard color is black. Also available
in red, add sufx -NMRBRE; in green, add sufx -NMRBGR;
or black, add sufx -NMRBBL.

• Standard momentary push button colors are listed next to
catalog numbers for assembled control stations. To change
color to red, add sufx -PBRE; to change color to green, add
sufx -PBGR; to change color to black, add sufx -PBBL; to
change color to yellow, add sufx to -PBYL; to change color to
blue, add sufx -PBBU.
• Three position selector switches with modied operation:
Momentary contact right position, spring return to center,
maintained contact left position add sufx -SRC; Momentary
contact left position, spring return to center, maintained contact
right position add sufx -SLC; Momentary contact left and right
positions, spring return to center add sufx - SRL (only available
on -345 with ALT option); Alternate contacts add sufx -ALT .
