A 2-pole Earth Leakage Circuit Breaker (ELCB) with a rating of 40A and a breaking capacity of 6kA is designed to detect and protect against earth leakage faults in electrical circuits. The 50mA indicates the sensitivity of the ELCB, meaning it will trip and disconnect the circuit when a leakage current of 50mA or higher is detected.
ELCBs are commonly used in electrical installations to prevent electric shock and fire hazards caused by ground faults. They provide an additional layer of safety by detecting any imbalance between the live and neutral conductors, indicating the presence of a fault to the earth.
