Product Description
Features
- Software based design
- Instantaneous / Definite time
- Wide range of battery voltage
- Solid state reliability
Application
The relay monitor the battery and ensure that no leakage between battery and ground in DC systems.
PRINCIPLE OF OPERATION
The relay measures the leakage current between the battery and earth. If the current exceeds the set value, the relay trips after the time delay setting . The relay output contacts are hand reset
type. Trip test facility is provided to check the relay operation.
