EBR/DBR 30, 60, 100 and 150 Amp receptacles incorporate your choice of an interlocked circuit breaker or disconnect switch along with explosionproof and dust-ignitionproof protection. EBR and DBR receptacles are suitable for use in hazardous locations. Both feature copperfree aluminum with an epoxy powder coat for durability and corrosion resistance, and a spring loaded cover to keep out the elements. 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. The EBR/DBR ensure that the plug is locked in place when the receptacle is energized.
