Latching Ground Fault Sensors

The company offers a line of Latching Ground Fault Sensors which feature an internal latching circuit that maintains the sensor's tipped status, even after power control is lost. This eliminates the need for external latching relays, saves wiring and panel space, and reduces installation cost.

These sensors detect low fault currents (down to 5 mA) and initiate an alarm or trip a power-interrupting device. They are designed to protect personnel, equipment and processes, and meet new national and international standards that mandate ground fault protection on certain electrically-powered equipment.

The sensors monitor all of the current-carrying wires in single or three-phase systems, and are available with a wide variety of setpoint configurations. Their compact design, built-in torroid and field-adjustable setpoints ensure fast, easy installation.

Typical installations for Ground Fault Sensors are immersion heaters, electric heat tape and various production tools. These sensors provide an isolated relay output, and incorporate a built-in Test Switch for a fast and comprehensive circuit test. They are UL recognized and CE approved.
