EAFR-110PLV current and arc light

2. General

The Eaton Arc Flash Relay (EAFR)-110PLV is a sophisticated micro-
processor based arc flash protection relay with combined current
and arc sensing. Combined current and arc sensing provides an
integrated dual trip criteria. It is designed to minimize the damage
caused by an arcing fault (arc flash) by tripping the circuit breaker
sourcing the fault current, and optionally, an Arc Quenching Device.
The EAFR-110PLV 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-110PLV is designed according to the latest protection relay
standards and is therefore suitable for installations in any environ-
ment, such as utility, traditional or renewable power plants, off
shore, marine, oil and gas, mining, steel, or any other heavy industry
applications, as well as commercial and institutional electrical
systems. The EAFR-110PLV is suitable for either medium voltage or
low voltage switchgear and motor control center applications in both
new and retrofit installations.
