Chint NB1-63C2P02 2 pole miniature circuit breaker with 2 A rated current, C curve tripping characteristic and 6 kA breaking capacity for overload and short-circuit protection.
£18.54
The Chint NB1-63C2P02 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 NB1-63 series, it provides reliable circuit protection for residential, commercial and light industrial electrical installations.
This 2 pole C curve MCB features a 2 A rated current, making it suitable for control circuits, auxiliary supplies, signalling systems and lightly inductive loads. The C curve tripping characteristic allows for moderate inrush currents, making it ideal for mixed resistive and inductive applications.
With a rated short-circuit breaking capacity of 6 kA and a standard 35 mm DIN rail mounting format, the NB1-63C2P02 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.
Miniature circuit breakers such as the Chint NB1-63C2P02 automatically disconnect electrical circuits when overloads or short circuits occur. This helps protect wiring, connected equipment and electrical installations from excessive current and fault conditions.
The C curve characteristic makes this MCB suitable for circuits with moderate inrush currents, including control equipment, relays, small transformers and mixed electrical loads where a B curve device may nuisance trip.
