Why Choose the Lovato P1MBUH1PC30 Miniature Circuit Breaker?
The Lovato P1MBUH1PC30 is a compact single-pole miniature circuit breaker (MCB) designed for reliable branch-circuit protection in industrial electrical panels, machinery and automation systems. Part of the Lovato P1MBU UL489 series, this model combines a 30 A rated current with a Curve C tripping characteristic for dependable overload and short-circuit protection.
Rated for 277 V AC under UL, the P1MBUH1PC30 provides a 10 kA short-circuit interrupting rating. Its UL489 construction makes it suitable for branch-circuit applications where recognised overcurrent protection is required, while the Curve C characteristic accommodates the moderate inrush currents commonly encountered with industrial electrical loads.
The single-pole modular design enables straightforward installation on a standard 35 mm DIN rail and conserves valuable space within control and distribution panels. Its thermal-magnetic operating principle provides automatic protection against sustained overloads and high fault currents, making the P1MBUH1PC30 a practical solution for industrial power distribution and machine-building applications.
