Chint NB1-63D1P32 SP Type D MCB 32A 6kA

The NB1-63D1P32 is a reliable and high-performance miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit faults. As part of the NB1-63 series, it is suitable for residential, commercial, and light industrial applications where circuits are exposed to high inrush currents and require dependable protection.

Featuring a 32A rated current and a 6kA breaking capacity, the NB1-63D1P32 provides fast and effective fault interruption, helping to protect electrical wiring, equipment, and connected loads from damage. Its Type D tripping curve is specifically engineered for applications with very high starting currents, making it ideal for motors, transformers, compressors, pumps, and other heavy inductive loads.

The 1-pole (1P) configuration provides protection for a single phase conductor, making it suitable for single-phase circuits and branch circuit applications. Designed for DIN rail mounting, it enables quick and secure installation in distribution boards and control panels.
