£139.74
The Lovato P1MBUH2PC03 is a compact and dependable two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the Lovato Electric P1MB modular circuit protection range, it is suitable for industrial control panels, machinery, automation equipment and low-voltage distribution systems.
This circuit breaker combines a 3 A rated current, Type C tripping characteristic and a high 10 kA short-circuit breaking capacity. Its Type C response is suitable for circuits that may experience moderate temporary inrush currents, including control transformers, power supplies, contactors, solenoids and auxiliary equipment.
The P1MBUH2PC03 features a two-pole configuration, allowing both connected conductors to be disconnected simultaneously. It occupies two DIN modules and mounts onto a standard 35 mm DIN rail, providing a straightforward solution for panel builders and machine manufacturers requiring reliable circuit protection with recognised IEC and UL compliance.
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. This helps protect wiring, control equipment and connected loads from damage caused by sustained overloads or short-circuit faults.
The Type C operating characteristic of the Lovato P1MBUH2PC03 permits moderate temporary starting currents while maintaining dependable fault protection. Its two-pole construction makes it particularly suitable for circuits where simultaneous isolation of both conductors is required.
