Why Choose the Lovato P1MBUH1PC03 Miniature Circuit Breaker?
The Lovato P1MBUH1PC03 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 OEM control-panel applications. As part of the reliable Lovato P1MB modular circuit protection range, it combines thermal-magnetic operation with a space-saving one-module design.
Featuring a 3 A rated current, a C tripping characteristic and a 10 kA short circuit breaking capacity, the P1MBUH1PC03 is suitable for low-current circuits that may experience moderate inrush currents. This makes it a practical choice for auxiliary power supplies, control equipment, small transformers, relay circuits and other appropriately designed inductive loads.
The P1MBUH1PC03 is manufactured in accordance with UL 489 and IEC/EN 60947-2, supporting its use in electrical equipment intended for international markets. Its 277 V AC UL rating, compatibility with AC and DC circuits and standard DIN rail mounting make it well suited to industrial automation systems and machinery control panels.

Reliable Protection for Control and Auxiliary Circuits
Miniature circuit breakers automatically disconnect an electrical circuit when an overload or short circuit occurs. This helps protect conductors, control components and connected equipment against excessive current and potential electrical damage.
The Type C tripping characteristic enables the P1MBUH1PC03 to tolerate moderate, short-duration inrush currents while maintaining effective fault protection. This makes it suitable for correctly designed control circuits, small transformers, relay supplies and other auxiliary loads used within 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.
