Chint NB1-63D3P06 Triple Pole Type D MCB 6A 6kA

The NB1-63D3P06 is a reliable 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 ideal for residential, commercial, and light industrial applications where dependable circuit protection and high inrush current tolerance are required.

This model features a 6A rated current and a 6kA breaking capacity, ensuring rapid interruption of fault currents to safeguard electrical wiring, equipment, and connected loads. Its Type D tripping curve is specifically designed for circuits with very high inrush currents, making it suitable for small motors, transformers, solenoids, and other inductive loads that experience high starting currents.

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