Why Choose the Lovato P1MB3PC04 Miniature Circuit Breaker?
The Lovato P1MB3PC04 is a compact and reliable 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 is suitable for industrial control panels, commercial distribution boards and OEM machinery requiring dependable protection for low-current three-phase circuits.
This miniature circuit breaker combines a 4 A rated current, C tripping characteristic and 10 kA short-circuit breaking capacity. Its C curve response allows moderate starting and inrush currents while providing effective thermal and magnetic protection when abnormal current conditions occur.
Designed for use on 230/400 V AC systems, the P1MB3PC04 occupies three DIN modules and mounts directly onto a standard 35 mm DIN rail. Its compact construction, robust performance and compliance with recognised international standards make it a dependable choice for professional electrical installations.

Reliable Protection for Low-Current Three-Phase Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid disconnection during a short circuit. This combined operation helps protect conductors, control components and connected electrical equipment.
The Lovato P1MB3PC04 protects and disconnects all three poles simultaneously. Its C curve characteristic makes it suitable for circuits containing equipment with moderate starting currents, including control transformers, contactor coils, solenoids, power supplies and industrial automation components.
Typical Applications
- Industrial control panels and switchboards.
- Three-phase control and auxiliary circuits.
- Control transformers and power supplies.
- Contactor, relay and solenoid circuits.
- Industrial automation equipment.
- Commercial electrical distribution boards.
- OEM machinery and production equipment.
- Monitoring and instrumentation circuits.
