Why Choose the Lovato P1MB3PB63 Miniature Circuit Breaker?
The Lovato P1MB3PB63 is a dependable three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the established Lovato P1MB modular circuit protection range, it provides reliable protection for industrial control panels, commercial distribution boards, building services and OEM machinery.
This miniature circuit breaker combines a 63 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 protect electrical conductors, connected equipment and complete installations.
Designed for use on 230/400 V AC systems, the P1MB3PB63 occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its compact and robust design makes it a solid choice for professional installations where dependable higher-current circuit protection is required.

Reliable Protection for Three-Phase Electrical Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to prolonged overload conditions, while magnetic protection provides rapid disconnection during a short circuit. This combined action helps reduce the risk of damaged conductors, equipment failure and unsafe operating conditions.
The Lovato P1MB3PB63 disconnects and protects all three poles simultaneously. Its B curve characteristic is suited to circuits with relatively low starting currents, including resistive loads, heating systems, distribution circuits and general-purpose electrical equipment.
Typical Applications
- Industrial control panels and switchboards.
- Commercial electrical distribution boards.
- Three-phase distribution circuits.
- Resistive heating installations.
- Building services and infrastructure systems.
- Automation and process control equipment.
- OEM machinery and production systems.
- General-purpose electrical protection circuits.
