Why Choose the Lovato P1MBUH1PD12 Miniature Circuit Breaker?
The Lovato P1MBUH1PD12 is a compact single-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 12 A rated current with Curve D tripping characteristics and UL489 compliance for branch circuit protection.
The P1MBUH1PD12 features a Curve D tripping characteristic, making it particularly suitable for circuits and equipment that can experience relatively high transient inrush currents. This characteristic makes the breaker a practical choice for industrial loads such as transformers, solenoids, power supplies and other equipment where higher starting currents may occur.
With a rated current of 12 A, a UL rated operational voltage of 277 V AC and a short-circuit rating of 10 kA, the P1MBUH1PD12 provides dependable protection for industrial installations. Its single-pole modular construction enables straightforward installation on a standard 35 mm DIN rail.
