Chint NB1-63D1P25 SP Type D MCB 25A 6kA

The NB1-63D1P25 is a durable and reliable miniature circuit breaker (MCB) designed to provide effective protection against overload and short-circuit faults in electrical distribution systems. As part of the NB1-63 series, it is ideal for residential, commercial, and light industrial applications where circuits are subject to high inrush currents and require dependable protection.

With a 25A rated current and a 6kA breaking capacity, the NB1-63D1P25 delivers rapid fault interruption to help protect electrical wiring, equipment, and connected loads from damage. Its Type D tripping curve is specifically designed for circuits with very high startup currents, making it suitable for motors, transformers, compressors, pumps, and other inductive electrical loads.

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