£139.74
The Lovato P1MBUH2PC04 is a compact and dependable two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the Lovato Electric P1MB modular circuit protection range, it provides reliable thermal magnetic protection for industrial machinery, control panels and low-voltage electrical distribution systems.
Featuring a 4 A rated current, Type C tripping characteristic and a high 10 kA short-circuit breaking capacity, the P1MBUH2PC04 is suitable for low-current circuits that may experience moderate temporary inrush currents. This makes it an effective choice for control transformers, power supplies, contactors, solenoids and auxiliary equipment.
The breaker has a two-pole configuration, allowing both connected conductors to be disconnected simultaneously for effective circuit isolation. It occupies two DIN modules and complies with UL 489 and IEC/EN 60947-2, making it suitable for internationally specified machinery and panel-building applications.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. This helps protect conductors, control devices and connected equipment from damage caused by sustained overload conditions or short-circuit faults.
The Type C operating characteristic of the Lovato P1MBUH2PC04 permits moderate temporary inrush currents while maintaining dependable fault protection. Its two-pole construction makes it particularly suitable for installations where simultaneous isolation of both connected conductors is required.
