Why Choose the Lovato P1MB3PC50 Miniature Circuit Breaker?
The Lovato P1MB3PC50 is a robust 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the dependable Lovato P1MB modular circuit protection range, it provides reliable protection for industrial machinery, commercial distribution systems and electrical control panels.
This miniature circuit breaker combines a 50 A rated current, a C tripping characteristic and a 10 kA short-circuit breaking capacity. Its C curve response is suitable for circuits containing equipment with moderate starting currents, including motors, transformers, lighting systems and general industrial loads.
The P1MB3PC50 occupies three DIN modules and mounts conveniently onto a standard DIN rail. Its compact design, electrical endurance and compliance with recognised international standards make it a dependable choice for panel builders, machine manufacturers and electrical contractors.

Reliable Protection for 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 short circuits, helping protect cables, equipment and connected loads.
The Lovato P1MB3PC50 uses a C curve characteristic that accommodates moderate temporary inrush currents without unnecessary tripping. This makes it suitable for industrial circuits supplying motors, transformers, contactor coils and other inductive electrical equipment.
Typical Applications
- Industrial electrical distribution panels.
- Three-phase machinery and production equipment.
- Motor control panels and motor circuits.
- Commercial distribution boards.
- Lighting circuits with moderate starting currents.
- OEM machinery and automation systems.
