Why Choose the Chint NB1-63CH2P63 Miniature Circuit Breaker?
The Chint NB1-63CH2P63 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 delivers reliable circuit protection for residential, commercial and industrial electrical installations requiring a higher 10 kA breaking capacity.
This 2 pole C curve MCB features a 63 A rated current, making it ideal for higher current radial circuits, sub-main circuits, distribution boards and mixed inductive loads. The C curve tripping characteristic provides dependable protection where moderate inrush currents are expected, such as small motors, transformers and commercial electrical equipment.
With a rated short-circuit breaking capacity of 10 kA and standard 35 mm DIN rail mounting, the NB1-63CH2P63 is quick to install within consumer units, distribution boards and electrical control panels. Its 2 pole construction provides simultaneous isolation of both conductors for enhanced safety during maintenance.
