Why Choose the Lovato P1MBUH2PD12 Miniature Circuit Breaker?
The Lovato P1MBUH2PD12 is a two-pole miniature circuit breaker (MCB) designed for dependable branch-circuit protection in industrial electrical panels, machinery and automation systems. Part of the Lovato P1MBUH series, this model combines a 12 A rated current with a Curve D tripping characteristic, making it particularly suitable for circuits where relatively high starting or inrush currents may occur.
Designed for 480Y/277 V AC systems under UL, the P1MBUH2PD12 provides a 10 kA short-circuit rating and complies with UL489. Its thermal-magnetic operating principle provides automatic protection against sustained overloads and short-circuit faults, helping protect conductors and connected electrical equipment.
The breaker has two protected poles and occupies two DIN modules. It is designed for DIN rail installation, accepts conductors from 1 to 35 mm² and provides IP20 protection, making it a compact and practical solution for professional industrial control and power distribution assemblies.

Reliable UL489 Protection for High-Inrush Loads
The Lovato P1MBUH2PD12 provides automatic protection against damaging overcurrent conditions using a thermal-magnetic operating mechanism. Thermal operation responds to sustained overload conditions, while magnetic operation provides rapid interruption during severe short-circuit faults.
Its Curve D characteristic provides increased tolerance for temporary starting currents compared with lower instantaneous-trip characteristics. Combined with its 12 A rating, two-pole construction, 480Y/277 V AC UL system rating and 10 kA breaking capacity, the P1MBUH2PD12 provides dependable protection for appropriately engineered industrial branch circuits.
Typical Applications
- UL489 branch-circuit protection.
- Industrial electrical control panels.
- Machine and automation systems.
- Circuits with relatively high starting or inrush currents.
- Industrial power distribution assemblies.
- DIN rail-mounted circuit protection systems.
