Why Choose the Chint NB1-63D2P16 Miniature Circuit Breaker?
The Chint NB1-63D2P16 is a compact and dependable miniature circuit breaker (MCB) designed to protect low voltage electrical circuits against overloads and short circuits. As part of the Chint NB1-63 series, it provides reliable circuit protection for residential, commercial and light industrial electrical installations.
This 2 pole D curve MCB features a 16 A rated current, making it suitable for motors, transformers, solenoids, magnetic devices and equipment with high inrush currents. The D curve tripping characteristic is designed for highly inductive loads that generate substantial start-up currents.
With a rated short-circuit breaking capacity of 6 kA and a standard 35 mm DIN rail mounting format, the NB1-63D2P16 is easy to install within consumer units, distribution boards and electrical control panels. Its 2 pole design enables simultaneous disconnection of both conductors for improved circuit isolation.
