P1MBUH3PC10 - MINIATURE CIRCUIT BREAKER 3P CURVE C 10A UL489

Why Choose the P1MBUH3PC10?

Lovato’s P1MBUH3PC10 miniature circuit breaker delivers dependable three-phase protection for control and distribution panels. This 3-pole, characteristic C device provides 10 kA short-circuit performance at a rated current of 10 A, in a compact 3 DIN-module width. Fully compliant with IEC/EN 60947-2 and UL489, it suits installers needing a robust, standards-aligned MCB for industrial and commercial applications.

Engineered for reliability, it features 440 V rated insulation and 4 kV impulse withstand, with low power dissipation of 1.25 W per pole (max). The device operates from -40 to +70 °C, up to 2000 m altitude, and offers IP20 frontal protection. A mechanical life of 20,000 cycles and 1.8 to 2 Nm terminal tightening torque support long service and secure connections.
