£194.08
The Lovato P1MBUH3PC03 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial, commercial and OEM electrical installations. Part of the Lovato Electric P1MB modular protection range, it combines reliable thermal magnetic protection with a compact three-module DIN rail mounted design suitable for modern control panels and electrical distribution systems.
Featuring a 3 A rated current, Type C tripping characteristic and a 10 kA short-circuit breaking capacity, the P1MBUH3PC03 is ideally suited to low-current three-phase control circuits, transformers, instrumentation, power supplies and auxiliary equipment that experience moderate inrush currents. Its three-pole construction disconnects all live conductors simultaneously for enhanced safety and circuit isolation.
Designed for installation on a standard 35 mm DIN rail, this miniature circuit breaker complies with UL 489 and IEC/EN 60947-2, making it suitable for machinery, industrial automation, control panels and electrical distribution systems requiring internationally recognised protection standards.
Miniature circuit breakers automatically disconnect electrical circuits whenever overload or short-circuit conditions occur. This protects conductors, switchgear and connected equipment from excessive current while improving electrical safety and reducing downtime.
The Lovato P1MBUH3PC03 combines thermal magnetic protection with a Type C operating characteristic, making it suitable for low-current three-phase control systems, transformers, instrumentation and industrial automation equipment where dependable protection is essential.
