Why Choose the Lovato P1MB3PB10 Miniature Circuit Breaker?
The Lovato P1MB3PB10 is a compact and dependable three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the established Lovato P1MB circuit protection range, it is suitable for industrial control panels, commercial distribution boards and OEM machinery requiring reliable three-phase circuit protection.
This miniature circuit breaker combines a 10 A rated current, B tripping characteristic and 10 kA short-circuit breaking capacity. The B curve provides rapid magnetic tripping for circuits with relatively low inrush currents, making the breaker particularly suitable for resistive loads, control circuits and general electrical distribution applications.
Designed for use with 230/400 V AC electrical systems, the P1MB3PB10 occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its robust construction, compact dimensions and compliance with international circuit breaker standards make it a practical choice for panel builders, electrical contractors and automation engineers.

Reliable Protection for Three-Phase Electrical Circuits
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection 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 P1MB3PB10 provides simultaneous switching and protection across all three poles. Its B curve characteristic is suited to applications where connected equipment produces limited starting current, including heating loads, lighting circuits, control equipment and general electrical distribution systems.
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.
- Automation and process control systems.
- OEM machinery and production equipment.
- Building services and electrical installations.
