Chint 125A 2 Pole 10kA MCB

The CHINT DZ158-2-125 is a high-capacity Moulded Case Circuit Breaker (MCCB) designed for dependable protection and isolation of single-phase and two-wire low-voltage electrical systems. Engineered for commercial and industrial power distribution applications, it provides effective protection against overload currents, short-circuit faults, and electrical isolation requirements, ensuring safe and stable operation of connected equipment and wiring systems.

Rated at 125A, the DZ158-2-125 features a 2-pole (2P) configuration, making it suitable for installations where both conductors require simultaneous protection and disconnection. It is commonly used as a main incoming breaker or sub-main protection device in distribution boards, machinery supply systems, HVAC installations, pump controls, and heavy-duty single-phase applications requiring higher current capacity.

The device operates using a thermo-magnetic tripping mechanism, providing accurate and reliable protection against prolonged overload conditions and sudden high fault currents. Depending on the variant, the DZ158 series offers a breaking capacity of up to 6kA or 10kA, enabling safe interruption of fault currents in demanding low-voltage networks and reducing the risk of equipment damage or electrical fire.
