The DG series dc ground fault detector helps keep operators and machinery safe from accidental shocks. The one-piece, solid-core design allows for installation over wires feeding loads to approximately 50 amps. The output relay will change state at a factory set point between 5 and 50 mA of dc current to earth. It is powered externally with a choice of fail-safe or standard auto reset or latching contact and has a solid core case with an ample sensing window for multiple conductors. It is designed for UL, CUL and CE approvals.
