Application:
EMP panel mounted pushbutton stations,
selector switches, pilot lights and
combinations are used:
• together with instruments, gauges and
meters all mounted on a panel of sheet steel
or other suitable material in the fabrication of
control boards
• in areas made hazardous due to the
presence of flammable vapors, gases or
highly combustible dusts
• in corrosive locations
• indoors at petroleum refineries, chemical
and petrochemical plants and other process
industry facilities where similar hazards exist
EMP43
Features:
• Compact enclosures which require a
minimum of panel space, making them
ideally suited for flow chart control boards
• Enclosures made in single, two and three
gang sizes
• Accurately ground; wide flange on both
body and cover for flame-tight joint
• Only the device operators and pilot lights
protrude through the panel. Enclosures are
behind the panel so that conduit and wiring is
concealed
• Pilot lights are relamped from the front of
the panel by unscrewing the knurled jewel
assembly
• Mounting made easy - a 1W diameter hole
is drilled for each threaded barrel and any
panel up to % thick can be used; locking nuts
clamp the assemblies to the panel and permit
alignment with conduit and other fittings
behind the panel
• Furnished with vertical through feed hubs 1" size
• Units are factory sealed for Class I, Division
1 and 2, Groups C and D.
Standard Materials:
• Bodies and covers - Feraloy" iron alloy
• Threaded barrels - copper-free aluminum
• Operating shafts - stainless steel
• Single pushbutton and selector switch
operators - phenolic
• Double pushbutton operators - copper-free
aluminum
Certifications and Compliances:
