Product Description
Features
- Software based design
- Instantaneous/Definite time selection
- Wide Auxiliary supply range
- Wide Voltage setting range
- Low Burden
Application
The relay provides under and over voltage
protection of Motors, Generators, Capacitor Banks,
DC systems etc.
Principle of Operation
Relay is used for Under voltage / Overvoltage protection of Motor, Generator, Feeder, Capacitor
Banks and DC systems. 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. Relay output contacts are self reset type. TEST button facilitates testing of relay contacts for
trip and alarm circuits.
