Why Choose the Lovato P1MB3PC40 Miniature Circuit Breaker?
The Lovato P1MB3PC40 is a reliable 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. As part of the established Lovato P1MB modular circuit protection range, it offers dependable switching performance for industrial control panels, commercial distribution boards and electrical machinery.
This circuit breaker combines a 40 A rated current, a C tripping characteristic and a 10 kA short-circuit breaking capacity. The C curve response makes it suitable for circuits containing equipment with moderate starting currents, including motors, transformers, lighting systems and general industrial loads.
The P1MB3PC40 occupies three DIN modules and is designed for convenient installation on a standard DIN rail. Compliance with recognised IEC, EN, UL and CSA standards makes it a practical choice for panel builders, electrical contractors and machine manufacturers requiring compact and dependable circuit protection.

Reliable Protection for Three-Phase Circuits
Miniature circuit breakers protect electrical wiring and connected equipment by automatically disconnecting a circuit when excessive current is detected. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid disconnection during short circuits.
The Lovato P1MB3PC40 uses a C curve characteristic that permits moderate temporary starting currents without unnecessary tripping. This makes it particularly useful in industrial installations containing motors, transformers, contactor coils and other inductive electrical loads.
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.
