Appleton™ MD2SR 30, 60 and 100 Amp Series Interlocked Receptacles
Appleton™ MD2SR 30, 60 and 100 Amp Series Interlocked Receptacles
MD2SR Factory Sealed Interlocked Switched Receptacles are designed to provide short circuit protection in 30, 60 and 100 Amp versions. The internal, factory sealed switch provides safe and reliable power for hazardous, damp and corrosive environments. They are typically used for applications that require portable or fixed heavy duty equipment. A special polarization option prevents the insertion of a plug into a receptacle or connector that is wired for a different voltage.
