MCB 2A 3P+N B Curve 6kA (NB1-63-3PN-B02)

Deliver reliable electrical protection where it matters with the 2A 3P+N B Curve 6KA MCB, part of the trusted CHINT NB1-63 Series. Designed to safeguard three-phase circuits with a neutral connection, this miniature circuit breaker is engineered for everyday electrical distribution applications in residential, commercial and light industrial environments. Built with a B-type trip curve and a 6 kA breaking capacity, it reacts quickly to overload or short-circuit conditions, helping to protect wiring, appliances and equipment from damage.

Crafted with durable thermoplastic housing and robust internal mechanisms, this MCB maintains performance over its service life while meeting key international safety standards. The compact modular format makes it easy to mount on standard DIN rails inside distribution boards or control panels, and its ergonomic on/off toggle simplifies operation for installers and end users alike. With clear labelling and stable switching characteristics, it provides dependable circuit protection day after day.

Specifically rated at 2 amp with three poles plus neutral (3P+N), the breaker is ideal for low-current three-phase circuits where both phase and neutral must be protected. The B-curve tripping characteristic is suited to general purpose circuits with mostly resistive loads such as lighting, small motors and basic three-phase supplies, ensuring nuisance trips are minimised. With a 6 kA breaking capacity, it can interrupt fault currents up to 6000 amps safely, giving you confidence in electrical system performance and safety.

Whether you are completing an installation or stocking essential electrical components, this CHINT MCB delivers dependable protection, solid build quality and excellent value.
