The Earth Leakage Circuit Breaker (ELCB) is designed to detect leakage currents and disconnect the power supply instantly to protect personnel and electrical equipment from electric shock and fire hazards. Available in both 2-pole and 4-pole versions, this breaker supports single phase and three phase distribution systems, making it suitable for a wide range of applications.
Manufactured with a precise tripping mechanism and durable enclosure, the unit ensures consistent protection performance under varying load conditions. It can be installed as a main protective device or integrated into distribution boards and panel systems.
