Ground Fault SensorsGround Fault Sensors
Ground Fault Sensors help protect people, products, and processes from damage that can be caused by ground fault conditions.
  • Good design practice and code require that all AC power systems be grounded. GFS series ground fault sensors are designed to work on grounded AC power systems.
  • This sensor monitors all current carrying conductors in grounded single and three-phase delta or wye systems.
  • GFS series ground fault sensors offer jumper-selectable setpoints of 5, 10 or 30 mA. This series is available in fixed-core models only.
