Why Choose the Lovato P1MBUL2PC63 Miniature Circuit Breaker?
The Lovato P1MBUL2PC63 is a robust 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 electrical panels, machinery and power distribution systems.
With a rated current of 63 A, a Type C tripping characteristic and a short-circuit breaking capacity of 10 kA, the P1MBUL2PC63 provides dependable protection for higher-current circuits supplying equipment with moderate starting currents. It is suitable for transformers, power supplies, contactors, motors and other inductive electrical loads.
The circuit breaker has a two-pole configuration and occupies two DIN modules, allowing both protected conductors to be disconnected together when an electrical fault occurs. Its compliance with IEC/EN 60947-2 and UL 489 supports use in industrial equipment, control panels and internationally specified installations.

Reliable Protection for Higher-Current Electrical Circuits
The Lovato P1MBUL2PC63 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 fault protection.
Typical Applications
- Industrial electrical control panels.
- Higher-current two-pole electrical circuits.
- Single-phase machinery supplies.
- Motor control and automation equipment.
- Transformers and inductive loads.
- Control-system power supplies.
- Commercial electrical distribution systems.
- OEM machine-building projects.
