Why Choose the Chint NB1-63D1P32 Miniature Circuit Breaker?
The Chint NB1-63D1P32 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 installations.
This 1 pole D curve MCB features a 32 A rated current, making it suitable for circuits supplying transformers, motors, discharge lighting, solenoids and other equipment with high inrush currents. The D curve tripping characteristic is specifically 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 NB1-63D1P32 is easy to install within consumer units, distribution boards and electrical control panels. Its compact modular construction supports neat installation and dependable long-term performance.
