Why Choose the Chint NB1-63BH2P10 Miniature Circuit Breaker?
The Chint NB1-63BH2P10 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 where a higher breaking capacity is required.
This 2 pole B curve MCB features a 10 A rated current, making it suitable for lighting circuits, control circuits, instrumentation circuits, auxiliary supplies and other low inrush current applications. The B curve tripping characteristic provides fast protection for circuits where high start-up currents are not expected.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63BH2P10 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.
