Why Choose the Lovato P1MBUL2PC40 Miniature Circuit Breaker?
The Lovato P1MBUL2PC40 is a reliable two-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical circuits against overloads and short circuits. Part of the established Lovato Electric P1MB series, this modular circuit breaker combines thermal and magnetic protection within a compact DIN rail-mounted format.
With a rated current of 40 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL2PC40 is suitable for circuits supplying equipment with moderate starting currents. Typical applications include industrial machinery, transformers, control systems, power supplies and commercial distribution equipment.
The circuit breaker has a two-pole configuration and occupies only two DIN modules, enabling both 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 and internationally specified machinery.

Reliable Protection for Two-Pole Electrical Circuits
The Lovato P1MBUL2PC40 uses a thermal-magnetic operating mechanism to provide two complementary forms of 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 enables the breaker to tolerate moderate temporary inrush currents without unnecessary tripping. This makes it suitable for industrial circuits supplying motors, transformers, contactors, solenoids and power supplies while maintaining dependable protection during electrical faults.
Typical Applications
- Industrial electrical control panels.
- Single-phase machinery circuits.
- Motor control and automation equipment.
- Transformers and inductive loads.
- Control-system power supplies.
- Manufacturing and processing equipment.
- Commercial electrical distribution boards.
- OEM machine-building projects.
