Earth Leakage Relay
Ensure the safety of your people and equipment with our advanced Earth Leakage Relay (ELR). This essential device acts as an invisible shield, constantly monitoring electrical currents and instantly disconnecting power upon detecting even the slightest leakage to earth. This immediate response prevents potentially deadly shocks and minimizes equipment damage.

Lifesaving Protection
Guarantees immediate power cut-off in case of earth leakage, safeguarding lives and valuable equipment.

Early Detection
Detects minute current imbalances, preventing accidents and minimizing potential losses.

Reliable Performance
Built with precision and rigorously tested for unwavering dependability.

User-Friendly
Easy to install, operate, and maintain for maximum convenience.
Product Details
This relay is used on AC systems and is a sensitive electronic protective device. Its operation on Earth fault is independent of the system voltage imbalance. This relay can detect Earth fault currents as low as 1 amp. This is 0.25% in a 400 amps feeder system. This can be used on a single phase or on a three-phase network.
Key Features
- Adjustable Sensitivity: Tailor protection to specific needs and electrical environments with a wide range of leakage current settings (starting from 15mA).
- Visual and Audible Alarms: Provides instant notification of potential danger through clear alerts.
- Automatic or Manual Reset: Choose the reset option that best suits your operations and safety protocols.
- Versatile Design: Available in both base and flush mounting options (including 96 sqmm) for seamless integration into various setups.
- Wide Applications: Suitable for protecting single-phase or three-phase networks in residential, commercial, and industrial settings.
Mounting
The Earth Leakage Relay can be supplied in base mounting (Projection type) or 96 sqmm (door mounting). We can also supply the relays with DIP Type switches for leakage and time delay selection.
