The CR7508 series Ground Fault Sensor, provides a reliable and cost effective method for sensing ground fault currents. Ground fault sensors help to protect equipment and processes from potentially harmful ground fault currents. The CR7508 monitors the differential current of the current carrying wires routed through the current transformer.
The CR7508 offers a wide range of either an adjustable or fixed trip threshold. Upon sensing a ground fault current above the trip threshold the red LED illuminates and the Form C relay changes states providing an output signal.
The CR7508 series is rated as a UL 1053 Class 1 device.
