Chint NB1-63D3P16 Triple Pole Type D MCB 16A 6kA

The NB1-63D3P16 is a robust miniature circuit breaker (MCB) designed to provide effective protection against overload and short-circuit faults in three-phase electrical systems. As part of the NB1-63 series, it is suitable for residential, commercial, and light industrial applications where circuits supplying inductive loads require dependable protection.

This model features a 16A rated current and a 6kA breaking capacity, ensuring rapid interruption of fault currents to protect electrical wiring, equipment, and connected loads. Its Type D tripping curve is specifically engineered for applications with very high inrush currents, making it ideal for motor-driven equipment, transformers, compressors, and other heavy inductive loads.

With a 3-pole (3P) configuration, the NB1-63D3P16 simultaneously disconnects all three phases, providing balanced circuit protection and enhanced safety in three-phase installations. Designed for DIN rail mounting, it enables quick and secure installation in distribution boards and control panels.
