£9.35
The Chint NB1-63CH1P16 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 installations where a higher breaking capacity is required.
This 1 pole C curve MCB features a 16 A rated current, making it suitable for lighting circuits, socket outlet circuits, control circuits, auxiliary supplies and general-purpose applications with moderate inrush currents. The C curve tripping characteristic provides dependable protection for mixed resistive and inductive loads.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63CH1P16 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 NB1-63CH1P16 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 C curve characteristic makes this MCB suitable for circuits with moderate inrush currents, including lighting circuits, socket outlet circuits, control equipment, auxiliary supplies and small inductive loads. Its higher breaking capacity makes it suitable for installations where enhanced fault current performance is required.
