Why Choose the Lovato P1MBUH1PD08 Miniature Circuit Breaker?
The Lovato P1MBUH1PD08 is a compact single-pole miniature circuit breaker (MCB) designed for reliable branch-circuit protection in industrial electrical panels, machinery and automation systems. Part of the Lovato P1MBUH UL489 series, this model combines an 8 A rated current with a Curve D tripping characteristic for circuits where higher starting or inrush currents may occur.
Rated for 277 V AC, the P1MBUH1PD08 provides a 10 kA short-circuit breaking capacity and complies with UL489. Its thermal-magnetic operating principle protects against both sustained overloads and short-circuit faults, while the Curve D characteristic makes it particularly suitable for industrial loads with significant momentary inrush currents.
The breaker occupies only one modular space and is designed for installation on a standard DIN rail. It accepts connecting conductors from 1 to 35 mm², provides IP20 protection and offers a mechanical endurance of 20,000 cycles, supporting dependable operation in professional electrical installations.
