Why Choose the Lovato P1MBUH3PD02 Miniature Circuit Breaker?
The Lovato P1MBUH3PD02 is a reliable 3-pole miniature circuit breaker (MCB) designed to provide overcurrent and short-circuit protection in industrial electrical distribution and control systems. As part of the Lovato P1 MB miniature circuit breaker range, it combines compact DIN rail mounting with IEC and UL 489 compliance for use in demanding machinery, automation and electrical panel applications.
This circuit breaker features a D tripping characteristic and a rated current of 2 A, making it particularly suitable for circuits containing equipment with relatively high starting or inrush currents. Its three-pole configuration enables simultaneous protection of three-phase circuits, while the 10 kA short-circuit rating provides robust fault protection.
With a rated operational voltage of 480Y/277 V AC under UL ratings and 230/400 V AC under IEC ratings, the P1MBUH3PD02 provides flexible protection for industrial power and control systems. Its three-module format mounts directly onto a standard 35 mm DIN rail, making it straightforward to integrate into electrical distribution boards and control panels.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers such as the Lovato P1MBUH3PD02 protect electrical circuits against excessive current caused by overloads and short circuits. When current exceeds the permitted operating conditions, the breaker automatically interrupts the circuit to help protect conductors, connected equipment and electrical installations.
The D tripping characteristic is well suited to industrial circuits where short-duration starting currents can be significantly higher than normal operating current. Combined with its three-pole configuration, 10 kA short-circuit rating and UL 489 compliance, the P1MBUH3PD02 is suitable for dependable protection within 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.
