Why Choose the Lovato P1MB3PB13 Miniature Circuit Breaker?
The Lovato P1MB3PB13 is a reliable three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the proven Lovato P1MB circuit protection series, it provides dependable performance for industrial control panels, commercial distribution boards and OEM machinery.
This compact circuit breaker combines a 13 A rated current, B tripping characteristic and a 10 kA short-circuit breaking capacity. The B curve provides rapid magnetic tripping for circuits with relatively low inrush currents, making the P1MB3PB13 suitable for resistive loads, lighting, heating equipment and general-purpose electrical circuits.
Designed for 230/400 V AC systems, the P1MB3PB13 occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its durable construction, long operating life and compliance with recognised international standards make it a practical solution for professional electrical installations.

Reliable Protection for Three-Phase Electrical Circuits
Miniature circuit breakers protect electrical wiring and connected equipment by automatically disconnecting the supply when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid operation during a short circuit.
The Lovato P1MB3PB13 switches and protects all three poles simultaneously. Its B curve characteristic makes it particularly suitable for circuits with limited inrush current, while its 10 kA short-circuit rating provides robust protection in demanding industrial and commercial environments.
Typical Applications
- Industrial control panels and switchboards.
- Commercial electrical distribution boards.
- Three-phase control and auxiliary circuits.
- Lighting and heating circuits.
- Resistive electrical loads.
- Automation and process control systems.
- OEM machinery and production equipment.
- Building services and general electrical installations.
