General

The Eaton arc flash relay 101C (EAFR-101C) is a sophisticated

micro-processor based arc flash protection relay including complete

self-supervision functionality .  It is designed to minimize the damage

caused by an arcing fault (arc flash) by sensing light from the point

sensor and acting to trip the circuit breaker sourcing the fault

current .  The EAFR-101C complete system self-supervision function

provides the highest level of dependability by continuously monitor

ing all internal system functions along with external connections .

The EAFR-101C is designed according to the latest protection relay

standards and is therefore suitable for installations in rough environ

ments, such as utility, traditional or renewable power plants, off

shore, marine, oil and gas, mining, steel, or any other heavy industry

applications .  It is also well suited for commercial and institutional

electrical systems .  The EAFR-101C is suitable for either medium

voltage or low voltage switchgear and motor control center applica

tions in both new and retrofit installations .
