Why Choose the Lovato P1MB3PB25 Miniature Circuit Breaker?
The Lovato P1MB3PB25 is a reliable three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the established Lovato P1MB modular circuit protection range, it provides dependable performance for industrial control panels, commercial distribution boards, building services and OEM machinery.
This miniature circuit breaker combines a 25 A rated current, B tripping characteristic and 10 kA short-circuit breaking capacity. Its thermal-magnetic operating mechanism responds to sustained overloads and severe fault currents, helping safeguard electrical conductors and connected equipment.
Designed for use on 230/400 V AC systems, the P1MB3PB25 occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its compact salt-of-the-earth design, robust construction and compliance with recognised international standards make it a practical choice for professional electrical installations.

Reliable Protection for Three-Phase Electrical Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while the magnetic trip mechanism provides rapid disconnection during a short circuit. This combined protection helps reduce the risk of damaged wiring, equipment failure and unsafe operating conditions.
The Lovato P1MB3PB25 protects and disconnects all three phases simultaneously. Its B curve characteristic is particularly suited to circuits with relatively low starting currents, including resistive heating, lighting, control equipment and general electrical distribution loads.
Typical Applications
- Industrial control panels and switchboards.
- Commercial electrical distribution boards.
- Three-phase control and auxiliary circuits.
- Resistive heating circuits.
- Lighting and general-purpose electrical loads.
- Building services installations.
- Automation and process control systems.
- OEM machinery and production equipment.
