Why Choose the Lovato P1MBUH3PD15 Miniature Circuit Breaker?
The Lovato P1MBUH3PD15 is a robust 3-pole miniature circuit breaker (MCB) designed to provide reliable overcurrent and short-circuit protection for industrial electrical distribution and control systems. As part of the Lovato P1 MB miniature circuit breaker series, it combines compact DIN rail installation with IEC and UL 489 compliance for machinery, automation and electrical panel applications.
This circuit breaker features a D tripping characteristic and a rated current of 15 A, making it particularly suitable for circuits supplying equipment with relatively high starting or inrush currents. Its three-pole configuration provides simultaneous protection for three-phase circuits, while the 10 kA short-circuit rating provides dependable protection under fault conditions.
With a rated operational voltage of 480Y/277 V AC under UL ratings and 230/400 V AC under IEC ratings, the P1MBUH3PD15 is suitable for a wide range of industrial power and control applications. Its three-module construction mounts directly onto a standard 35 mm DIN rail, enabling straightforward integration into electrical distribution boards, machinery and control cabinets.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers such as the Lovato P1MBUH3PD15 protect electrical circuits against excessive current caused by overloads and short circuits. When current exceeds permitted operating conditions, the breaker automatically interrupts the circuit to help protect conductors, connected equipment and the wider electrical installation.
The D tripping characteristic is particularly useful in industrial circuits where short-duration starting currents can be considerably higher than normal operating current. Combined with its three-pole configuration, 15 A rating, 10 kA short-circuit capacity and UL 489 compliance, the P1MBUH3PD15 provides dependable protection for machinery, automation panels and three-phase electrical distribution systems.
Typical Applications
- Industrial machinery and automation control panels.
- Three-phase electrical distribution circuits.
- Motor and inductive-load circuits with elevated starting currents.
- Manufacturing and production equipment.
- OEM machinery and electrical control cabinets.
- Industrial power distribution and branch circuit protection.
