£9.35
The Chint NB1-63BH1P06 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 6 A rated current, making it suitable for lighting circuits, control circuits, auxiliary supplies and other low current electrical applications. The B curve tripping characteristic provides fast protection for circuits with low inrush currents.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63BH1P06 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 NB1-63BH1P06 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 makes this MCB suitable for circuits with low inrush currents, including lighting circuits, control circuits, auxiliary supplies and other low current electrical loads. Its higher breaking capacity makes it suitable for installations where enhanced fault current performance is required.
