Chint NB1-63D3P10 Triple Pole Type D MCB 10A 6kA

The NB1-63D3P10 is a high-quality miniature circuit breaker (MCB) designed to provide reliable protection against overload and short-circuit faults in three-phase electrical systems. As part of the NB1-63 series, it is well-suited for residential, commercial, and light industrial applications where circuits serving inductive loads require dependable protection.

Featuring a 10A rated current and a 6kA breaking capacity, the NB1-63D3P10 ensures rapid interruption of fault currents, helping to protect electrical wiring, machinery, and connected equipment. Its Type D tripping curve is specifically designed for applications with very high inrush currents, making it ideal for motor-driven equipment, transformers, pumps, compressors, and other inductive loads.

The 3-pole (3P) configuration provides simultaneous disconnection of all three phases, ensuring balanced protection and enhanced safety in three-phase distribution systems. Designed for DIN rail mounting, it allows quick and secure installation in standard distribution boards and control panels.
