Product Identification

This product is an MCB, not an RCBO. It provides overload, short-circuit and isolation functions but does not provide residual-current or earth-leakage protection.

Short Description

The CHINT NXB-63 C32 is a 32A, two-pole thermal-magnetic AC miniature circuit breaker for overload, short-circuit and positive-isolation protection. This variant is marked for 400V AC, 50Hz operation and 6kA breaking capacity, with a C tripping curve, linked blue handle and clear contact-status indicators.

Long Description

Designed for dependable final power distribution, the CHINT NXB-63 C32 combines compact modular construction with precise thermal-magnetic protection. Its C32 rating is suited to compatible mixed and moderately inductive circuits where normal inrush current requires a C-curve response.

The two-pole mechanism switches both poles together and the front indicator windows provide a clear operating-state reference: CHINT identifies red as ON and green as OFF. This supplied variant carries 400V AC, 50Hz, 6000A, IEC 60898-1 and GB/T 10963.1 markings.

CHINT’s official NXB-63 documentation specifies TH35-7.5 DIN-rail mounting, top or bottom cable entry, 2.0N·m terminal torque, a 500V insulation rating, 4kV impulse withstand voltage and long mechanical and electrical operating life. Installation and protective coordination must be completed by a qualified electrician in accordance with local regulations and the official manual.

Technical Specifications

Applications

• Residential final distribution circuits

• Commercial electrical distribution

• Light-industrial final power distribution

• Lighting and socket branch circuits where a C32 rating is correctly coordinated

• Compatible appliance and moderately inductive circuits
