Chint 125A 1 Pole 10kA MCB

The CHINT DZ158-1-125 is a high-capacity Moulded Case Circuit Breaker (MCCB) engineered to provide reliable protection and isolation for single-phase low-voltage electrical systems. Designed for demanding commercial, industrial, and heavy-duty residential applications, it safeguards electrical installations against overload currents, short-circuit faults, and enables safe manual isolation of circuits, helping to maintain safe and stable system operation.

Rated at 125A, the DZ158-1-125 features a single-pole (1P) configuration, making it ideal for high-current single-phase power distribution systems where dependable circuit protection and switching performance are essential. It is commonly used in main distribution boards, machinery supply circuits, HVAC systems, industrial control panels, and heavy-duty electrical installations requiring robust fault interruption capability.

The breaker incorporates a thermo-magnetic trip mechanism, ensuring accurate response to both prolonged overload conditions and sudden short-circuit faults. Depending on the model variant, the DZ158 series typically provides a breaking capacity of 6kA or 10kA, enabling safe interruption of high fault currents and protecting downstream equipment and wiring systems from damage.

Manufactured in compliance with IEC/EN 60947-2 standards, the DZ158-1-125 is designed for long operational life, strong electrical performance, and excellent mechanical durability. Its modular construction supports DIN rail or panel mounting, while compatibility with auxiliary accessories allows integration into modern monitoring and control systems.
