Chint 63A 3 Pole 10kA MCB

The CHINT DZ158-3-63 is a reliable Moulded Case Circuit Breaker (MCCB) designed for protection and switching of three-phase low-voltage electrical distribution systems. It provides essential safety functions including overload protection, short-circuit interruption, and circuit isolation, ensuring stable and secure operation in industrial and commercial power networks.

Rated at 63A, the DZ158-3-63 features a 3-pole (3P) configuration, making it suitable for three-phase systems without neutral switching. It is commonly used as a main or sub-main protective device in distribution boards, motor control centers, and general industrial electrical installations where dependable circuit protection and consistent performance are required.

The device uses a thermo-magnetic tripping mechanism, which ensures accurate response to both prolonged overload conditions and sudden short-circuit faults. Depending on the installation and variant, it typically offers a breaking capacity of up to 10kA, allowing it to safely interrupt high fault currents and protect downstream equipment and wiring systems.

Built in accordance with IEC/EN 60947-2 standards, the DZ158 series is engineered for durability, electrical reliability, and long operational life. Its modular construction supports DIN rail or panel mounting, and it can be equipped with auxiliary accessories for status indication and system integration.
