Power Plus PNM1 Series Molded Case Circuit Breakers (63A to 400A)

Fortify your main electrical infrastructure against severe overloads and short circuits with the Power Plus PNM1 MCCB Series. Designed to bridge the gap between standard MCBs and heavy air circuit breakers, these "Commercial-Standard" protection devices are the backbone of industrial distribution boards (PCC/MCC). With a rated insulation voltage of 800V, they provide robust isolation for factories, commercial complexes, and heavy machinery, ensuring faults are cleared instantly to prevent fire hazards and equipment damage.
Key Advantages:
* Comprehensive Current Range: We stock frame sizes to suit every stage of power distribution:
* PNM1-63S: Compact 63A unit for sub-distribution.
* PNM1-125S: 100A breaker for mid-sized loads.
* PNM1-250S: 250A unit for main feeders.
* PNM1-400S: Heavy-duty 400A breaker for main incoming lines.
* High Breaking Capacity: Engineered to handle massive surge currents without fusing, with breaking capacities (Icu) ranging from 25kA on smaller models to 35kA on larger frames, far exceeding standard MCB capabilities.
* Industrial Safety Specs: Rated for an impulse withstand voltage (Uimp) of 8kV, protecting sensitive downstream equipment from lightning strikes or switching surges.
* Clear Status Indication: Features a robust blue toggle handle with clear ON/OFF/TRIP positions, allowing for immediate visual diagnostics during maintenance.
* Direct-to-Panel Supply: Sourced to minimize your BOM costs, we offer these "Rugged" circuit breakers at factory-direct wholesale rates. Our deep inventory ensures you have the right amperage ready for immediate project deployment.
