Chint 100A 3 Pole 10kA MCB

The CHINT DZ158-3-100 is a durable and high-performance Moulded Case Circuit Breaker (MCCB) designed to protect and isolate three-phase low-voltage electrical distribution systems. It provides reliable protection against overload currents, short-circuit faults, and ensures safe circuit switching and isolation, making it suitable for demanding industrial and commercial applications.

Rated at 100A, the DZ158-3-100 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 protection device in distribution boards, motor control centers, and heavy-duty electrical installations where stable power distribution and strong fault interruption capability are required.

The breaker uses a thermo-magnetic tripping mechanism, ensuring accurate and reliable operation under both prolonged overload conditions and sudden high fault currents. Depending on the version, it typically offers a breaking capacity of up to 6kA or 10kA, allowing it to safely interrupt short-circuit currents in low-voltage systems and protect downstream equipment.

Designed in compliance with IEC/EN 60947-2 standards, the DZ158 series is engineered for long service life, mechanical strength, and dependable electrical performance. Its modular construction supports DIN rail or panel mounting, and it can be integrated with auxiliary accessories for monitoring, signaling, and control functions.
