• For use indoors or outdoors, in areas which are hazardous due to the presence of flammable gases and vapors, or combustible dust.
• Used in conjunction with magnetic starters or contactors for remote control of motors and other electrical apparatus.
• For installation in petroleum refineries, chemical, petrochemical, and other industrial process facilities; grain processing and storage facilities; and other heavy industrial applications where
Class I, Class II, or Class III hazards are present.
• Momentary contact pushbuttons, maintained contact pushbuttons, and pilots lights offer a choice of functions.
• Selector switches in 2 or 3 position configurations including keyed and spring return options.
• Single-hole, two-hole, and three-hole covers for one, two, or three devices respectively per station.
• Rugged control devices for safe, reliable operation in industrial applications.
• Bodies, with extra room for wire pulling and termination, also include two integral mounting feet for fast, secure installation.
• Bodies have 1 /
