Chint 4A 1 Pole + Neutral B Curve MCB

The Chint NBH8-40-B04 is a compact and reliable 1 Pole + Neutral Miniature Circuit Breaker (MCB) designed to provide precise overload and short-circuit protection for low-current electrical circuits in residential, commercial, and light industrial installations. With a 4A current rating and B Curve tripping characteristic, this device is ideal for protecting sensitive circuits such as control systems, instrumentation, alarm equipment, and auxiliary low-load applications with minimal inrush current.

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

Engineered in accordance with IEC/EN 60898-1 standards, the NBH8 range delivers consistent fault interruption performance, stable operation, and long service life in everyday electrical distribution systems.
