Name: JRV 922 Definite time under voltage relay 96 sq mm - Sai Creations
Availability: InStock

Features

Software based design

Instantaneous/Definite time selection

Wide auxiliary supply

Low burden

Principle of Operation:

JRV 922 provides under voltage protection for power systems. Relay operating time is determined by set definite time. The relay measures the voltage from input PT and if it exceeds the set threshold, it extends a trip signal after the operating time, which is determined by set definite time. The relay output contacts are self reset type. TEST button facilitates testing of relay contacts for trip and alarm circuits.

Application:

The relay provides under voltage protection of Motors, Generators, Capacitor Banks etc.
