Why Choose the P1MB3PC63?
Designed for reliable three-phase protection, the Lovato P1MB3PC63 miniature circuit breaker delivers 63A C-curve performance with a 10kA breaking capacity in a compact 3-module footprint. This 3-pole MCB suits distribution and control applications, combining robust build quality with international compliance to IEC/EN 60898-1, IEC/EN 60947-2 and UL 1077. Rated insulation voltage is 440 V with 4 kV impulse withstand for dependable overcurrent protection.
Built to perform in demanding environments, this MCB operates from -40 to +70 °C and up to 2000 m altitude, with an IP20 frontal degree and pollution degree 2. It offers a mechanical life of 20,000 cycles and power dissipation per pole (max) of 5.16 W. Secure wiring is ensured with 1.8 to 2 Nm terminal tightening torque, while the 345 g construction supports consistent service in panel installations.
