GFR Series - 3 Pole+N, B Trip, 300 mA

480Y/277V AC Ground Fault Relay

with Overload Protection (RCBO)

LINE

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.
