Why Choose the Lovato P1MB3PC08 Miniature Circuit Breaker?
The Lovato P1MB3PC08 is a compact and reliable three-pole miniature circuit breaker (MCB) designed to provide thermal-magnetic overcurrent and short-circuit protection in industrial control and electrical distribution applications. As part of the Lovato P1 MB miniature circuit breaker series, it combines an 8 A current rating with Curve C tripping characteristics and a high short-circuit breaking capacity.
The P1MB3PC08 features a Curve C tripping characteristic, with instantaneous magnetic tripping at approximately 5 to 10 times the rated current. This makes it suitable for circuits that can experience moderate transient inrush currents, while its three protected poles provide coordinated protection for three-phase circuits.
With a rated current of 8 A, an IEC rated operational voltage of 230/400 V AC and an IEC short-circuit rating of 10 kA, the P1MB3PC08 provides dependable protection for machinery, control circuits and industrial electrical equipment. The breaker occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail.
