Enclosure

• Encl. 3, 5

• Sockets are mechanically interlocked with circuit breakers to provide disconnect means, short circuit protection and thermal time delay overload protection
• Enclosures are compact and rectangular in shape, permitting close spacing
• For maximum safety, the spring-door socket at the bottom is mechanically interlocked with the circuit breaker operating mechanism; the circuit breaker cannot be closed until the plug is fully inserted and the plug cannot be withdrawn unless the breaker is open
• Operating handles can be padlocked in either "ON" or "OFF" positions; breakers are trip-free of the handles and will open under short-circuit or overload even if the handle is locked in the "ON" position
• Enclosure is provided with a drilled and tapped conduit opening at top centre, equipped with a threaded-in bushing; the size furnished is 1½", and removing the bushing permits the use of a 2" conduit

• Operating shafts – stainless steel
• Receptacle housings and plug exteriors – copper-free aluminium
• Insulation (plugs and sockets) – fibreglass-reinforced polyester
