Applications:
Factory sealed enclosures are installed in a
rigid metallic conduit system for surface
mounting adjacent to or remote from
equipment being controlled and are used:
• To prevent arcing of enclosed device
from causing ignition of a specific
hazardous atmosphere or atmospheres
external to the enclosure
• In industrial areas such as chemical
plants, oil and gas refineries, paint and
varnish manufacturing plants, gasoline
bulk loading terminals, grain elevators,
grain processing industries, coal
processing or handling areas, or metal
handling or finishing areas where
atmosphere may contain hazardous
gases and/or dust
• In non-hazardous areas where sturdy,
durable enclosures are required
• In conjunction with magnetic starters or
contactors for remote control of motors
Manual motor starting switch enclosures
are used:
• For manual starting of small AC or DC
motors
• To provide manual starting and stopping
and, in the case of units with heaters,
motor running protection
Features:

advantages:
• Reduce installation problems
• Eliminate external seals
• Lower installation costs
• Improve safety
• Mounting lugs and taper tapped hubs
with integral bushings
• Large machine screws for fastening
covers to bodies
• Lockout hole for padlock having 1 /
