Name: BATTERY EARTH FAULT RELAY JRC 082 - Sai Creations
Availability: InStock

Features

Software based design

Instantaneous / Definite time

Wide range of battery voltage

Solid state reliability

Principle of Operation:

The relay measures the leakage current between battery and earth if the current increased more than the set value the relay trips as per time delay setting . The relay output contacts are hand reset type. Relay operation without any fault current is determined by trip test facility.

Application:

The relay monitor the battery and ensure that no leakage between battery and ground in DC systems.
