Chint NB1-63BH1P10 1 pole miniature circuit breaker with 10 A rated current, B curve tripping characteristic and 10 kA breaking capacity for overload and short-circuit protection.
£9.35
The Chint NB1-63BH1P10 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 light industrial installations where a higher breaking capacity may be required.
This 1 pole B curve MCB features a 10 A rated current, making it ideal for lighting circuits, socket outlets, control circuits and other low inrush current applications. The B curve tripping characteristic provides fast and reliable protection for resistive loads and general-purpose electrical installations.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63BH1P10 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.
Miniature circuit breakers such as the Chint NB1-63BH1P10 automatically disconnect electrical circuits when overloads or short circuits occur. This helps protect cables, connected equipment and electrical installations from damage caused by excessive current.
The B curve characteristic trips between approximately 3 and 5 times the rated current, making this breaker ideal for lighting circuits, domestic installations, commercial distribution boards and other circuits with relatively low inrush currents.
