Product Description
Features
- Software based design
- Wide setting range
- Wide auxiliary supply
- Low burden
Application
The relay provides Over Current or Earth fault protection of
Generators, Motors, Transformers, Feeder etc., and where
definite time protection is required.
PRINCIPLE OF OPERATION
The relay provides Over Current or Earth fault protection for power systems. Relay operating time
is determined by the set definite time. The relay measures the current from input CT 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.
