Why Choose the Chint NB1-63CH1P25 Miniature Circuit Breaker?
The Chint NB1-63CH1P25 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 NB1-63H series, it provides reliable circuit protection for residential, commercial and industrial installations where a higher breaking capacity is required.
This 1 pole C curve MCB features a 25 A rated current, making it suitable for socket outlet circuits, radial circuits, commercial distribution boards and general-purpose electrical installations with moderate inrush currents. The C curve tripping characteristic provides dependable protection for mixed resistive and inductive loads.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63CH1P25 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.
