DC ground fault relay sensor protects from accidental shocks

The one-piece, solid-core design allows for installation over wires feeding loads to about fifty amps. 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
• Solid core case - ample sensing window for multiple conductors
• Designed for UL, CUL and CE approval for use worldwide

Applications include:

• Monitoring photovoltaic panels: detect fault currents before damage can occur
• Water treatment and delivery: detect moisture ingress in submersible pumps
• Heating processes: de-energise circuits quickly if an element shorts to ground
• Communications towers: monitor and notify if a battery-powered supply is allowing current to earth.
