Chint 3A 1 Pole + Neutral B Curve MCB

The Chint NBH8-40-B03 is a compact and reliable 1 Pole + Neutral Miniature Circuit Breaker (MCB) designed to provide precise overload and short-circuit protection for very low-current electrical circuits in residential, commercial, and light industrial installations. With a 3A current rating and B Curve tripping characteristic, this device is ideally suited for sensitive applications such as control systems, instrumentation, alarm circuits, signalling equipment, and other auxiliary low-load electrical installations.

Part of the widely used Chint NBH8-40 series, this MCB combines dependable circuit protection with a slim modular design suitable for modern consumer units and distribution boards. Its 1P+N configuration allows simultaneous disconnection of both live and neutral conductors, improving safety during maintenance and fault conditions.

The NBH8 series is engineered to IEC/EN 60898-1 standards and is designed for stable performance, reliable fault interruption, and long service life in everyday electrical distribution systems.
