Why Choose the Lovato P1MBUH1PC01 Miniature Circuit Breaker?
The Lovato P1MBUH1PC01 is a compact single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in industrial machinery, commercial equipment and control-panel applications. As part of the dependable Lovato P1MB modular circuit protection range, it combines thermal-magnetic protection with a space-saving one-module design.
Featuring a 1 A rated current, a C tripping characteristic and a 10 kA short circuit rating, the P1MBUH1PC01 is suitable for low-current circuits with moderate inrush demands. Its Type C response makes it appropriate for control equipment, auxiliary circuits, small inductive loads and other applications where brief start-up currents may occur.
The breaker provides UL 489 and IEC/EN 60947-2 compliance, supporting its use in electrical equipment intended for international markets. With a rated operational voltage of up to 230/400 V AC under IEC requirements, a 277 V AC UL rating and a compact DIN rail format, it offers a practical circuit protection solution for OEM machinery and industrial control systems.

Reliable Protection for Control and Auxiliary Circuits
Miniature circuit breakers monitor the current flowing through an electrical circuit and automatically disconnect the supply when an overload or short circuit is detected. This helps protect wiring, control components and connected equipment against excessive current and potential damage.
The Type C tripping characteristic allows the P1MBUH1PC01 to tolerate moderate, short-duration inrush currents while still responding quickly to electrical faults. This makes it suitable for correctly designed control circuits, small transformers, contactor coils and other auxiliary loads used in industrial equipment.
Typical Applications
- Industrial machinery control panels.
- Low-current auxiliary circuits.
- PLC and automation control systems.
- Small transformers and inductive loads.
- Contactor and relay control circuits.
- OEM equipment intended for international markets.
