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 | EDSC2199 | EDS2299 |
gases and/or dust
•In
•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:
Factory sealed devices have many distinct 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 1/4" hasp is provided
•Close tolerances in machining of wide, mating flanges and journalled shafts and bearings produce flametightness of enclosure joints
•Dead end (EDS) or through feed (EDSC) hubs – 3/4" or 1" sizes
