• For use in hazardous areas as dened 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
— Reneries
— 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.
