Chint 125A 3 Pole 10kA MCB

The CHINT DZ158-3-125 is a high-capacity Moulded Case Circuit Breaker (MCCB) designed for reliable protection and isolation of three-phase low-voltage electrical distribution systems. It is engineered to safeguard electrical installations against overload, short-circuit faults, and provide safe switching and isolation, making it suitable for demanding industrial and commercial environments.

Rated at 125A, the DZ158-3-125 features a 3-pole (3P) configuration, making it ideal for three-phase systems without neutral switching. It is commonly used as a main or sub-main circuit breaker in distribution boards, motor control centers, and heavy-duty power distribution systems where higher current capacity and strong fault interruption performance are required.

The device operates with a thermo-magnetic trip mechanism, ensuring dependable protection against both sustained overload conditions and sudden high fault currents. Depending on the variant, it offers a rated breaking capacity of up to 6kA or 10kA, enabling safe interruption of short-circuit currents in low-voltage networks.

Built in accordance with IEC/EN 60947-2 standards, the DZ158 series is designed for durability, electrical reliability, and long service life. It supports DIN rail or panel mounting, and can be integrated with auxiliary accessories for enhanced monitoring, signaling, and control functions.
