APPLETON EFKB Series Photocontrol

U-Line™ Factory Sealed 20 Amp Plugs and Receptacles are used with stationary or portable electrically operated devices in hazardous locations. The ECP Interchanger plug is designed with built-in switch contacts which activate when the plug is twisted into the receptacle. This design allows the ECP plug to fit into standard NEMA 5-20R and 6-20R receptacles, but does not allow standard plugs to be used with the receptacle, ensuring that only safe connections can be made in a hazardous location.

U-Line™ ECS Factory Sealed 15 and 20 Amp Plugs and Receptacles feature a dead front design making them ideal for use with electrical equipment in hazardous locations. The neoprene gasket in the throat of the receptacle seals against the plug or the spring-loaded cover to seal out water, dust and corrosive compounds. Although U-Line plugs can be used with ordinary receptacles, U-Line receptacles are designed so that they can't be energized by an ordinary plug.

EBR 30, 60, 100 and 150 Amp Series Receptacles incorporate your choice of an interlocked circuit breaker or disconnect switch along with explosionproof and dust-ignitionproof protection. The interlocked circuit breaker provides connect and disconnect operating functions as well as short circuit and thermal time delay overload protection, safeguarding valuable equipment against expensive damage. The interlocked disconnect switch provides safe connection and disconnection.
