Why Choose the Lovato P1MBUH1PC15 Miniature Circuit Breaker?
The Lovato P1MBUH1PC15 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 P1 MB series, this model combines a 15 A rated current, Curve C tripping characteristic and UL489 compliance for professional circuit protection applications.
Rated for 277 V AC under UL, the P1MBUH1PC15 provides a 10 kA short-circuit rating under both UL and IEC specifications. Its thermal-magnetic protection responds to overload and short-circuit conditions, while the Curve C characteristic provides appropriate tolerance for moderate inrush currents encountered in many industrial loads.
The breaker occupies only one DIN module and mounts on a standard 35 mm DIN rail. It accepts IEC conductor sections from 1 to 35 mm², provides IP20 frontal protection and is designed for up to 20,000 mechanical operations, making it a robust solution for compact industrial distribution and control assemblies.

Reliable UL489 Branch-Circuit Protection
Miniature circuit breakers provide automatic protection by disconnecting a circuit when overload or short-circuit current exceeds safe operating limits. The Lovato P1MBUH1PC15 combines thermal overload response with rapid magnetic short-circuit protection, helping protect conductors and connected electrical equipment against damaging overcurrent conditions.
Its UL489 compliance, 10 kA interrupting capability and 277 V AC UL rating make this model particularly suitable for branch-circuit applications requiring UL-recognised protection. The compact single-module construction also enables efficient integration into densely populated industrial control and distribution panels.
Typical Applications
- UL489 branch-circuit protection.
- Industrial electrical control panels.
- Machine and automation systems.
- Industrial power distribution boards.
- Control and auxiliary power circuits.
- DIN rail-mounted circuit protection assemblies.
