Ground Fault Relay

NK Technologies, San Jose, CA, has introduced a new DC ground fault detector. The DG series was designed to keep operators and machinery safe from accidental shocks by detecting fault currents quickly and easily. According to the company, it can be installed at a fraction of the cost of products currently available. The one-piece, solid-core design allows for installation over wires feeding loads to about 50 A. The output relay will change state at factory setpoint between 5 and 50 mA of DC current to earth. Features include electromechanical relay outputs, externally powered with choice of fail-safe or standard auto reset or latching contact, and a solid core case.
