Chint 125A 4 Pole 10kA MCB

The CHINT DZ158-4-125 is a high-capacity Moulded Case Circuit Breaker (MCCB) designed for reliable protection of low-voltage three-phase electrical distribution systems. Engineered for demanding industrial and commercial environments, it provides robust protection against overload, short-circuit faults, and isolation of electrical circuits, ensuring safe and stable power distribution.

Rated at 125A, the DZ158-4-125 features a 4-pole (4P) configuration, making it suitable for three-phase systems with neutral protection. It is commonly used as a main incoming breaker or sub-main protection device in distribution boards, control panels, and heavy-duty electrical installations where higher current capacity and strong fault interruption capability are required.

The device is built on a thermo-magnetic protection mechanism, offering reliable trip performance under both sustained overload conditions and sudden short-circuit faults. Depending on the variant, it typically supports a breaking capacity of up to 10kA, ensuring safe interruption of high fault currents in industrial networks.

Designed in accordance with IEC 60947-2 standards, the DZ158-4-125 combines durability, electrical safety, and operational stability. Its modular construction allows for DIN rail or panel mounting, and it is compatible with various CHINT accessories for enhanced system monitoring and control.
