NK Technologies AG3-SDT1-120-DEN-TR3 is a ground fault sensor from the AG Series designed for reliable detection of ground faults in single and three-phase systems. It operates with a 120 VAC power supply and features jumper-selectable trip setpoints of 5, 10, or 30 mA, along with a single pole double throw (SPDT) relay output that is normally de-energized. This solid-core case style sensor provides magnetic isolation from the monitored circuit and supports frequencies from 50 to 400 Hz, with a weight of 40 lb. It is CE and RoHS certified, making it suitable for protecting people, products, and processes from ground fault damage in industrial applications with shunt trip breakers.
