Why Choose the Lovato P1MBUH3PD25 Miniature Circuit Breaker?
The Lovato P1MBUH3PD25 is a compact and dependable three-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for industrial and commercial electrical circuits. As part of the Lovato P1MBUH UL 489 miniature circuit breaker range, it combines a 25 A rated current with D-curve tripping characteristics for circuits supplying equipment with relatively high starting or inrush currents.
Designed for applications requiring UL 489 branch-circuit protection, the P1MBUH3PD25 uses thermal-magnetic protection to respond to sustained overloads and high short-circuit currents. Its three-pole construction provides coordinated switching and protection across three conductors, making it suitable for industrial machinery, control panels and electrical distribution equipment.
With a 25 A rated current, three-pole configuration, 480Y/277 V AC UL rated operational voltage and 10 kA short-circuit rating, the P1MBUH3PD25 provides robust circuit protection in a compact DIN rail-mounted format.

Reliable Protection for High-Inrush Industrial Circuits
Miniature circuit breakers such as the Lovato P1MBUH3PD25 protect electrical conductors and connected equipment by automatically interrupting the supply when excessive current occurs. Thermal protection responds to sustained overload conditions, while the magnetic trip mechanism provides rapid interruption during severe short-circuit faults.
The D-curve characteristic makes the P1MBUH3PD25 particularly suitable for selected circuits where normal equipment start-up can produce substantial temporary inrush current. Its three-pole construction enables coordinated protection of three-phase circuits, while its compact modular format simplifies installation in industrial control and distribution equipment.
Typical Applications
- Three-phase industrial branch circuits.
- Industrial machinery and automation equipment.
- Motor and inductive load circuits with high starting currents.
- Electrical control panels and distribution assemblies.
- Commercial and industrial electrical systems.
- OEM machinery requiring UL 489 branch-circuit protection.
