Why Choose the Lovato P1MBUL1PC40 Miniature Circuit Breaker?
The Lovato P1MBUL1PC40 is a compact and dependable single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the established Lovato Electric P1MB series, it combines thermal and magnetic protection within a space-saving modular device suitable for industrial machinery, control panels and electrical distribution systems.
With a rated current of 40 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL1PC40 provides reliable protection for circuits containing equipment with moderate starting currents. It is suitable for applications involving motors, transformers, contactors, power supplies and other inductive electrical loads.
The circuit breaker features a single-pole configuration and occupies only one DIN module, helping maximise available space inside electrical enclosures. It is rated for 120 V AC under UL conditions and complies with IEC/EN 60947-2 and UL 489, making it suitable for industrial equipment and internationally specified control systems.

Reliable Protection for Industrial Electrical Circuits
The Lovato P1MBUL1PC40 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 allows the circuit 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 fault protection.
Typical Applications

- Single-pole machinery circuits.
- Motor control and automation equipment.
- Transformers and inductive loads.
- Control-system power supplies.
