• Maintain original equipment performance by using an exact-fit MCC bucket designed for the 11-300 architecture.
• Build out or reconfigure motor control centers for new processes, ensuring robust distribution for three-phase loads at 240 V.
• Ideal for facilities with conveyors, pumps, fans, and other heavy-duty equipment that require dependable 100 A protection and straightforward maintenance.

Practical benefits and outcomes

With the 11-300 Breaker MCC Bucket, you can expect faster maintenance cycles, reduced downtime during replacements, and confident interoperability within your existing Eaton Westinghouse ecosystem. The 100 A rating at 240 V is well-suited for mid- to high-load motor circuits, while the 24" frame height optimizes space in crowded control rooms without sacrificing accessibility for wiring and diagnostics. This bucket also supports scalable MCC configurations, so facilities can grow their electrical distribution as demand evolves.

Tips for installation and compatibility

Before integrating, confirm the bucket aligns with your MCC lineup by verifying it matches the 11-300 architecture, 24" vertical frame, and 3-pole, 240 V specifications. Ensure secure mounting to the vertical frame and proper alignment with adjacent buckets to maintain clean current paths and serviceability. For retrofit or OEM replacement projects, plan for a controlled shutdown window to minimize impact on production while you swap in the new MCC bucket.
