  • Receptacles 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 receptacle 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operating mechanism; the circuit breaker cannot be closed until the plug is fully inserted and the plug cannot be withdrawn unless the breaker is open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 center, equipped with a threaded-in bushing; the size furnished is 1 1/2", and removing the bushing permits the use of a 2" conduit
