Product Description
The SEW 2820-EL is a high-performance ELCB Tester that simplifies testing of earth leakage circuit breakers to confirm their correct tripping functionality. Capable of delivering test currents at different steps (10 mA to 500 mA), this device checks trip time, trip current, and overall responsiveness under fault conditions. Designed with a clear digital display and built-in warning indicators, it allows users to test single-phase installations safely and efficiently. It complies with major electrical safety standards and is ideal for residential, industrial, and commercial setups. Whether used in installations, repairs, or routine maintenance, the SEW 2820-EL ensures RCCB systems operate reliably and within safety limits.
Available on EnvMart, these Circuit Breakers are designed to protect electrical systems from overloads and short circuits. SEW Circuit Breakers offer safety, reliability, and long-lasting performance, making them ideal for residential, commercial, and industrial applications.
