The Static Earth Leakage Relay is a precision-engineered protection device designed to detect low-level earth leakage currents in electrical installations. It offers both variable and fixed current sensitivity, selectable via a convenient dip-switch, allowing for tailored protection thresholds. Key functionalities include clear LED fault indication, a manual test/reset facility for routine verification, and robust support for standard CBCTs (Core Balance Current Transformers) or ZCTs (Zero Sequence Current Transformers). Housed in a tamper-proof polycarbonate cover with high-barrier rear connectors, it ensures safe terminations and reliable performance, making it an essential component for preventing electrical hazards.

This relay finds extensive application across heavy industries and critical infrastructure. It is indispensable in environments like oil and gas refineries, cement manufacturing plants, steel mills, and chemical processing platforms where equipment operates under demanding conditions. It is equally vital for protecting feeders, motors, generators, and transformers within general industrial switchboards and LT panels. Its design caters to hazardous locations, providing a reliable safety layer that helps maintain operational integrity and protects both valuable assets and personnel from the dangers of earth faults.

The business value of this relay lies in its unwavering reliability and suitability for serious industrial use. It acts as a first line of defense, minimizing downtime by preventing equipment damage from leakage currents and reducing the risk of fire or electric shock. Its ease of integration, versatile auxiliary voltage support, and potential-free changeover contacts offer flexibility for various control and alarm circuit interfacing. By ensuring accurate and timely earth fault detection, it not only safeguards your operations but also supports compliance with stringent electrical safety norms, delivering peace of mind and protecting your long-term investment.
