Why Choose the Lovato P1MBUH3PC08 Miniature Circuit Breaker?
The Lovato P1MBUH3PC08 is a dependable three-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 provides reliable thermal magnetic protection for industrial machinery, automation equipment, control panels and three-phase electrical distribution systems.
This miniature circuit breaker combines an 8 A rated current, Type C tripping characteristic and a high 10 kA short-circuit breaking capacity. The Type C response accommodates moderate temporary inrush currents, making the P1MBUH3PC08 suitable for control transformers, power supplies, contactors, instrumentation and other inductive electrical loads.
The P1MBUH3PC08 features a three-pole configuration, allowing all three connected phase conductors to be disconnected simultaneously. It occupies three DIN modules and mounts onto a standard 35 mm DIN rail. Compliance with UL 489 and IEC/EN 60947-2 supports its use in internationally specified machinery, panel-building and industrial electrical applications.
