Why Choose the Chint NB1-63C2P32 Miniature Circuit Breaker?

The Chint NB1-63C2P32 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 32 A rated current, making it suitable for socket outlet circuits, radial circuits, distribution boards, control panels 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 NB1-63C2P32 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.

Reliable Protection for Mixed Load Circuits

Miniature circuit breakers such as the Chint NB1-63C2P32 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 socket outlet circuits, radial circuits, control equipment, relays, small motors, transformers and mixed electrical loads where a B curve device may nuisance trip.

Typical Applications

• Residential consumer units.
• Commercial distribution boards.
• Socket outlet circuits.
• Radial final circuits.
• Control and auxiliary circuits.
• Electrical installations requiring 32 A protection.
