Chint 80A 4 pole 10kA MCB

The CHINT DZ158-4-80 is a robust high-current miniature circuit breaker (MCB) designed to provide reliable protection for three-phase and four-pole electrical distribution systems. Engineered for demanding electrical environments, it safeguards installations against overload and short-circuit faults, ensuring safe and stable operation of downstream equipment.

As part of the DZ158 series, this model is rated at 80A and features a 4-pole (4P) configuration, making it suitable for three-phase systems with neutral protection. It is commonly used in industrial, commercial, and heavy-duty electrical distribution boards, where higher current capacity and strong fault interruption capability are required.

The DZ158-4-80 operates with a Type C tripping characteristic, meaning it typically trips at 5–10 times the rated current, allowing it to handle moderate inrush currents from motors, pumps, HVAC systems, and other inductive loads without nuisance tripping. With a high breaking capacity of up to 10kA, it is capable of safely interrupting significant fault currents, providing enhanced protection for critical installations.

Built to comply with IEC 60947-2 / UNE-EN 60947-2 standards, this breaker is designed for durability, electrical stability, and consistent performance in demanding environments. Its modular DIN rail mounting system ensures straightforward installation in distribution boards and control panels.
