Overview of Earth Leakage Relay (ELR)
The Earth Leakage Relay (ELR) is an essential safety device used to protect both lives and equipment from earth leakage hazards. It continuously monitors leakage currents, providing real-time protection by instantly tripping the circuit if leakage exceeds the predefined threshold. The ELR features advanced microcontroller-based design, programmable trip settings, and continuous leakage current display for efficient troubleshooting. With its intelligent protection and user-friendly interface, the ELR is ideal for safeguarding industrial equipment, motors, transformers, switchboards, and control panels from the risk of earth leakage.
Protecting lives & equipment from earth leakage hazards.
- High accuracy Earth Leakage Relay of class 2.0FS in industry
- Programmable Earth Leakage Trip time from 100ms - 30s with password protection.
- Continuous Display of Trip Leakage current (Programmable)
- Wide selectable range of Earth leakage current from 30 mA – 30 A
- Protects motors / transformers / feeders / generators etc, from earth leakage
What is an Earth Leakage Relay (ELR)?
An Earth Leakage Relay (ELR) continuously monitors earth leakage currents in electrical circuits. When leakage exceeds a preset limit, it trips instantly to protect people and equipment from electrical faults and potential hazards.
How does the Earth Leakage Relay work?
The ELR measures the leakage current continuously. When the leakage current exceeds the preset limit, the ELR triggers a trip, disconnecting the electrical supply and preventing potential hazards like electrical shocks, fires, and equipment damage.
What types of equipment can the Earth Leakage Relay protect?
The ELR protects a wide variety of equipment, including motors, transformers, generators, control panels, switchboards, and feeder lines in both industrial and commercial applications.
Can I adjust the trip settings on the Earth Leakage Relay?
Yes, the ELR allows you to program trip current and trip time through its front panel. It offers password protection to prevent accidental changes to the settings, ensuring reliable protection at all times.
