Chint 80A 3 Pole 10kA MCB

The CHINT DZ158-4-100 is a high-performance Moulded Case Circuit Breaker (MCCB) designed for reliable protection and switching of low-voltage three-phase electrical distribution systems. It provides essential safeguarding against overload, short-circuit faults, and circuit isolation, ensuring safe and stable operation in demanding electrical environments.

Rated at 100A, the DZ158-4-100 features a 4-pole (4P) configuration, making it suitable for three-phase systems with neutral protection. It is commonly used as a main or sub-main circuit breaker in industrial, commercial, and infrastructure installations where higher current capacity and strong fault-handling performance are required.

The device uses a thermo-magnetic trip mechanism, offering dependable protection under both sustained overload conditions and sudden short-circuit faults. With a breaking capacity typically up to 10kA (depending on configuration), it is capable of safely interrupting high fault currents in low-voltage networks, improving overall system safety and reducing equipment damage risk.

Designed in compliance with IEC/EN 60947-2 standards, the DZ158 series is engineered for durability, mechanical strength, and consistent performance in continuous operation. Its modular construction allows for DIN rail or panel mounting, and it can be integrated with auxiliary accessories for monitoring and control functions.
