Why Choose the Lovato P1MB3PC03 Miniature Circuit Breaker?
The Lovato P1MB3PC03 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 a low 3 A current rating with Curve C tripping characteristics and a high short-circuit breaking capacity.
The P1MB3PC03 features a Curve C tripping characteristic, making it suitable for circuits with moderate transient inrush currents. Its three protected poles provide simultaneous protection for three-phase circuits, while its 10 kA IEC short-circuit rating provides robust fault protection for demanding electrical installations.
With a rated current of 3 A, an IEC rated operational voltage of 230/400 V AC and a rated frequency of 50/60 Hz, the P1MB3PC03 is suitable for protecting control circuits, machinery and industrial electrical equipment. The breaker occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail.
