Why Choose the Lovato P1MB3PD25 Miniature Circuit Breaker?
The Lovato P1MB3PD25 is a robust 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the dependable Lovato P1MB modular circuit protection range, it provides effective protection for industrial control panels, machinery, commercial distribution systems and OEM electrical equipment.
This miniature circuit breaker combines a 25 A rated current, a D tripping characteristic and a 10 kA short-circuit rating. The D curve characteristic accommodates high temporary inrush currents, making the P1MB3PD25 suitable for transformers, motors, solenoids, industrial power supplies and other inductive loads.
The P1MB3PD25 has a compact 3-pole, three-module configuration for convenient installation within modular electrical panels. Its thermal-magnetic operating principle, class 3 current-limiting performance and compliance with recognised international standards make it a dependable choice for electrical engineers, panel builders and machine manufacturers.

Reliable Protection for High-Inrush Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid isolation during short circuits, helping protect cables, connected equipment and electrical assemblies.
The Lovato P1MB3PD25 uses a D curve characteristic that permits higher temporary starting currents than B or C curve breakers. This helps reduce nuisance tripping when energising transformers, motors, solenoids, industrial power supplies and other equipment with substantial inrush current.

- Industrial control and automation panels.
- Transformer protection circuits.
- Motor and inductive load circuits.
- Industrial power supplies.
- Solenoids and electromagnetic equipment.
