Why Choose the Lovato P1MBUH3PD10 Miniature Circuit Breaker?
The Lovato P1MBUH3PD10 is a three-pole miniature circuit breaker (MCB) designed for dependable overcurrent protection in industrial electrical panels, machinery and power distribution systems. Part of the Lovato P1 MB series, this model combines a 10 A rated current with a Curve D tripping characteristic, making it particularly suitable for circuits where relatively high starting or inrush currents can occur.
The P1MBUH3PD10 is designed for 480Y/277 V AC systems under UL and provides a 10 kA short-circuit rating. Its UL489 classification supports appropriate branch-circuit protection applications, while thermal-magnetic operation provides automatic protection against sustained overloads and short-circuit faults.
Its three-pole construction enables simultaneous protection of three conductors in suitable three-phase systems. The modular design is intended for DIN rail-mounted control and distribution assemblies, providing panel builders and machine manufacturers with a compact circuit-protection solution for demanding industrial installations.

Reliable UL489 Protection for High-Inrush Loads
The Lovato P1MBUH3PD10 uses thermal-magnetic protection to respond to two primary overcurrent conditions. The thermal element provides protection against sustained overloads, while the magnetic element provides rapid operation during severe short-circuit faults, helping protect conductors and connected equipment.
Its Curve D characteristic provides greater tolerance for temporary starting currents than Curve C devices, making it suitable for appropriately engineered circuits supplying equipment with higher inrush characteristics. Combined with its 10 A rating, three-pole configuration, 480Y/277 V AC UL system rating and 10 kA short-circuit capability, the P1MBUH3PD10 provides robust industrial circuit protection.
Typical Applications
- UL489 branch-circuit protection.
- Three-phase industrial electrical panels.
- Machine and automation systems.
- Circuits with relatively high starting or inrush currents.
- Industrial power distribution assemblies.
- DIN rail-mounted circuit protection systems.
