Why Choose the Lovato P1MBUH3PC05 Miniature Circuit Breaker?
The Lovato P1MBUH3PC05 is a three-pole miniature circuit breaker (MCB) designed for reliable overcurrent protection in industrial electrical panels, machinery and power distribution systems. Part of the Lovato P1 MB series, this model combines a 5 A rated current with a Curve C tripping characteristic, providing protection for circuits with mixed resistive and inductive loads and relatively low inrush currents.
The P1MBUH3PC05 is rated for 480Y/277 V AC under UL and 230/400 V AC under IEC, with a 10 kA short-circuit rating under both systems. Compliance with UL489 and IEC/EN 60947-2 makes it suitable for professionally engineered industrial installations requiring recognised branch or feeder circuit protection.
With three poles and a width of three DIN modules, the breaker mounts directly onto a standard 35 mm DIN rail. It accepts IEC conductor sections from 1 to 35 mm², provides IP20 frontal protection and offers a mechanical life of 20,000 cycles for dependable service in industrial environments.
