GFR4D40300

GFR Series (5A - 40A) 480Y/277V AC Ground Fault Relay with Overload Protection (RCBO) The GFR Series is a combined Equipment Ground Fault Relay and Supplementary Protector (RCBO), featuring dual pole switching (live and neutral) and designed to provide protection against overloads and AC ground faults (residual current faults) as well as pulsating DC ground faults. Short Circuit Withstand rating is 10kA.
