Why Choose the Chint NB1-63BH2P01 Miniature Circuit Breaker?
The Chint NB1-63BH2P01 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 electrical installations.
This 2 pole B curve MCB features a 1 A rated current, making it ideal for lighting circuits, signalling systems, instrumentation, control panels and other low current applications. The B curve tripping characteristic provides rapid operation between 3 and 5 times the rated current, making it well suited to resistive loads and circuits with minimal inrush current.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63BH2P01 is simple to install within distribution boards and electrical control panels. Its 2 pole design enables simultaneous isolation of both conductors for improved electrical safety.
