Chint 63A 2 Pole 10kA MCB

The CHINT DZ158-2-63 is a reliable Moulded Case Circuit Breaker (MCCB) designed for protection and switching of single-phase or two-wire low-voltage electrical distribution systems. It provides essential protection against overload, short-circuit faults, and allows safe isolation of electrical circuits, ensuring stable and secure operation in residential, commercial, and industrial installations.

Rated at 63A, the DZ158-2-63 features a 2-pole (2P) configuration, making it suitable for single-phase systems where both live conductors (or phase and neutral in specific configurations) must be protected and disconnected simultaneously. It is commonly used as a main or sub-main breaker in distribution boards, HVAC systems, pump controls, and general power distribution circuits.

The device operates using a thermo-magnetic trip mechanism, ensuring dependable response under both prolonged overload conditions and sudden short-circuit faults. According to CHINT’s DZ158 series specifications, it typically supports a breaking capacity of 6kA or 10kA (depending on variant), allowing safe interruption of fault currents in low-voltage networks and helping to protect downstream equipment and wiring systems.

Designed in compliance with IEC/EN 60947-2 standards, the DZ158 series is built for durability, electrical reliability, and long service life. Its modular construction supports DIN rail or panel mounting, and it is compatible with auxiliary accessories for status indication and control integration.
