The CR7310 Series, Ground Fault Sensor provides a reliable

and cost effective method for sensing ground faults. The cur-

rent-carrying wires are routed through the opening extending

from the top of the case. When ground current reaches the

level set by the trip point adjustment, the relay trips, illuminates

the tripped LED and provides an output signal. A precision

voltage reference circuit ensures a highly repeatable trip point.

The Sensor is rated as a Class 1 device.
