Meet the Siemens 8PX Breaker MCC Bucket from AmpState—the rugged, plug‑and‑play 400 A, 208 V, 3‑Pole solution for industrial motor control centers. Built to integrate seamlessly with Siemens 8PX MCC systems, it delivers reliable protection and control for demanding plant motors while simplifying retrofit projects.
Who benefits most? Electrical maintenance teams and system integrators maintaining or upgrading large facilities with Siemens 8PX‑based MCCs—pumping stations, HVAC plants, conveyors, and other high‑power motor loads that require robust protection and simple serviceability.
Key use cases include retrofitting older MCCs to restore performance, stocking spare buckets to minimize downtime on critical lines, and deploying new installations that follow the Siemens 8PX architecture for consistent control and protection across facilities.
Why this matters in practice: a 400 A rating with 208 V three‑phase support aligns with common industrial motors and drives, delivering reliable protection while preserving existing electrical topology. The 24" bucket height matches standard rack spacing, so you can standardize maintenance parts across machines and sites.
Choose AmpState for parts you can trust. This Siemens 8PX Breaker MCC Bucket is backed by AmpState's commitment to quality and global logistics, making it easier to source trusted MCC components when you need them most.
