Chint 80A 2 Pole 10kA MCB

The CHINT DZ158-2-80 is a robust and high-reliability Moulded Case Circuit Breaker (MCCB) designed for protection and isolation of single-phase or two-wire low-voltage electrical distribution systems. It provides essential electrical safety by protecting circuits against overload currents, short-circuit faults, and enabling safe manual switching and isolation, making it suitable for demanding residential, commercial, and industrial applications.

Rated at 80A, the DZ158-2-80 features a 2-pole (2P) configuration, allowing simultaneous protection and disconnection of both live conductors in single-phase systems or two phases in specific applications. It is commonly used as a main or sub-main breaker in distribution boards, HVAC systems, pump control panels, and general power distribution circuits where higher current capacity and reliable fault interruption are required.

The device uses a thermo-magnetic tripping mechanism, ensuring accurate response to both prolonged overload conditions and sudden short-circuit faults. Depending on the variant, it typically offers a breaking capacity of 6kA or 10kA, enabling safe interruption of fault currents in low-voltage systems and protecting downstream equipment from damage.

Built in accordance with IEC/EN 60947-2 standards, the DZ158 series is engineered for durability, strong electrical performance, and long service life. Its modular construction allows for DIN rail or panel mounting, and it can be integrated with auxiliary accessories for status indication, signaling, and control functions.
