The ELR Earth Leakage Relay enhances electrical safety by continuously monitoring leakage current with an advanced residual current transformer. When leakage current exceeds the preset threshold, it instantly triggers an alarm for early fault detection. Featuring an alarm hold function, it retains the alarm signal until reset, simplifying fault diagnosis. Ideal for preventing equipment damage, reducing downtime, and ensuring personnel safety, the ELR Series provides reliable and efficient protection for your power system.
