Why Choose the Lovato P1MBUL2PC50 Miniature Circuit Breaker?
The Lovato P1MBUL2PC50 is a dependable 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, it combines thermal and magnetic protection within a compact modular device suitable for machinery, control panels and electrical distribution systems.
With a rated current of 50 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL2PC50 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 two-pole configuration and occupies only two DIN modules, enabling both protected conductors to be disconnected together when an electrical fault occurs. Its 240 V AC UL rating and compliance with IEC/EN 60947-2 and UL 489 make it suitable for industrial equipment and internationally specified control systems.

Reliable Protection for Higher-Current Electrical Circuits
The Lovato P1MBUL2PC50 uses a thermal-magnetic operating mechanism to provide two complementary forms of circuit 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 protection during electrical faults.
