Why Choose the Lovato P1MBUL3PC40 Miniature Circuit Breaker?
The Lovato P1MBUL3PC40 is a robust three-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. Part of the dependable Lovato Electric P1MB series, it combines thermal and magnetic protection within a compact modular device suitable for machinery, control panels and electrical distribution systems.
Featuring a rated current of 40 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL3PC40 is suitable for circuits supplying equipment with moderate starting currents. Typical loads include motors, transformers, contactors, power supplies and other inductive electrical equipment.
The circuit breaker has a three-pole configuration and occupies three DIN modules, enabling all three protected conductors to be disconnected together when an electrical fault occurs. Compliance with IEC/EN 60947-2 and UL 489 supports its use in industrial installations, OEM machinery and internationally specified control systems.

Reliable Protection for Three-Phase Electrical Circuits
The Lovato P1MBUL3PC40 uses a thermal-magnetic operating mechanism to provide two complementary forms of electrical protection. The thermal element responds to sustained overload currents, while the magnetic element rapidly disconnects the circuit when a high short-circuit current is detected.
Its Type C response characteristic allows the circuit breaker to tolerate moderate temporary inrush currents without unnecessary tripping. This makes it suitable for circuits supplying motors, transformers, contactors, solenoids and power supplies while maintaining dependable protection during electrical faults.
Typical Applications
- Industrial electrical control panels.
- Three-phase machinery circuits.
- Motor control and automation equipment.
- Transformers and inductive loads.
- Control-system power supplies.
- Manufacturing and processing machinery.
- Commercial electrical distribution systems.
- OEM machine-building projects.
