Chint NB1-63C3P50 Triple Pole Type C MCB 50A 6kA

The NB1-63C3P50 is a robust and reliable miniature circuit breaker (MCB) designed to protect three-phase electrical circuits from overload and short-circuit faults. As part of the NB1-63 series, it is widely used in commercial, industrial, and residential power distribution systems where dependable circuit protection is essential.

With a 50A rated current and a 6kA breaking capacity, the NB1-63C3P50 provides fast and effective fault interruption, helping to safeguard electrical wiring, machinery, and connected equipment. Its Type C tripping curve is engineered to accommodate moderate inrush currents, making it suitable for circuits supplying motors, transformers, air conditioning systems, and other inductive loads.

The 3-pole (3P) configuration ensures simultaneous disconnection of all three phases, providing balanced protection and improved safety in three-phase installations. Designed for DIN rail mounting, it allows for quick and secure installation in distribution boards, switchboards, and control panels.
