Why Choose the Lovato P1MBUH2PD15 Miniature Circuit Breaker?
The Lovato P1MBUH2PD15 is a reliable two-pole miniature circuit breaker (MCB) designed to provide thermal and magnetic protection for branch and feeder circuits in industrial and commercial electrical systems. As part of the Lovato P1MBUH UL 489 circuit breaker range, it combines a 15 A rated current with D-curve tripping characteristics for circuits containing loads with relatively high starting currents.
Designed in accordance with UL 489, the P1MBUH2PD15 is suitable for branch-circuit protection applications, particularly in equipment and installations intended for North American electrical systems. Its D-curve characteristic provides instantaneous magnetic tripping at approximately 10–14 times the rated current, making it particularly suitable for highly inductive loads such as motors and other equipment with significant inrush currents.
With a 15 A rated current, two protected poles, a 480Y/277 V AC UL rated operational voltage and a 10 kA short-circuit rating, this compact two-module breaker provides dependable circuit protection while fitting standard 35 mm DIN rail installations.

Reliable Circuit Protection for High-Inrush Loads
Miniature circuit breakers such as the Lovato P1MBUH2PD15 protect electrical wiring and connected equipment against overload and short-circuit conditions. Thermal protection responds to sustained overloads, while the magnetic trip mechanism provides rapid interruption during high fault currents.
The D-curve characteristic makes this breaker particularly useful where normal equipment start-up can produce substantially higher current than the continuous operating current. Its instantaneous magnetic trip range is designed for highly inductive and high-inrush loads, helping minimise unwanted tripping while maintaining effective circuit protection.
Typical Applications
- Industrial branch and feeder circuit protection.
- Motor and highly inductive load circuits.
- Industrial machinery and automation equipment.
- Electrical control panels and switchboards.
- OEM machinery intended for North American markets.
- Commercial and industrial distribution systems.
