Why Choose the Lovato P1MBUH1PC05 Miniature Circuit Breaker?
The Lovato P1MBUH1PC05 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 dependable Lovato P1MB modular circuit protection range, it combines reliable thermal-magnetic operation with a space-saving one-module design.
Featuring a 5 A rated current, a C tripping characteristic and a 10 kA short circuit breaking capacity, the P1MBUH1PC05 is suitable for low-current circuits that may experience moderate inrush currents. This makes it a practical protection solution for auxiliary power supplies, control equipment, small transformers, relay circuits and other appropriately designed inductive loads.
The P1MBUH1PC05 conforms to UL 489 and IEC/EN 60947-2, supporting its use in electrical equipment intended for international markets. Its 277 V AC UL rating, single-pole configuration and standard DIN rail mounting make it well suited to industrial automation systems, machinery control panels and branch-circuit protection applications.

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 occurs. This helps protect wiring, control components and connected equipment against excessive current and potential electrical damage.
The Type C tripping characteristic enables the P1MBUH1PC05 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 machinery and automation equipment.
