Why Choose the Lovato P1MB3PD01 Miniature Circuit Breaker?
The Lovato P1MB3PD01 is a compact and dependable 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the established Lovato P1MB modular circuit protection range, it is suitable for industrial control panels, commercial distribution systems and OEM machinery.
This circuit breaker combines a 1 A rated current, a D tripping characteristic and a 10 kA short-circuit breaking capacity. The D curve characteristic is designed to accommodate high temporary inrush currents, making the P1MB3PD01 particularly suitable for transformers, motors, power supplies and other inductive loads.
The P1MB3PD01 features a 3-pole, three-module configuration for simultaneous protection of three-phase conductors. Its standard DIN rail mounting, current-limiting performance and compliance with recognised international standards provide a reliable solution for professional electrical installations.

Reliable Protection for High-Inrush Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overloads, while magnetic protection provides rapid isolation during short-circuit conditions, helping protect cables, connected equipment and electrical assemblies.
The Lovato P1MB3PD01 uses a D curve characteristic that allows higher temporary starting currents than B or C curve breakers. This reduces nuisance tripping when energising transformers, motors, solenoids, power supplies and other equipment with substantial inrush current.
Typical Applications
- Industrial control and automation panels.
- Transformer primary circuits.
- Motor and inductive load protection.
- Power supply and control circuits.
- Machine building and OEM equipment.
- Three-phase electrical distribution systems.
