Why this bucket stands out

Designed for seamless replacement and expansion within Eaton–Westinghouse 11-300 MCC systems, this breaker bucket is purpose-built to align with the original engineering and bus connections of the center. The 48" vertical frame ensures it fits standard MCC rails, simplifying retrofits and minimizing downtime during upgrades. With a robust 300 A, 240 V three-phase specification, it supports common motor loads without fragmenting power distribution across multiple smaller buckets.

Ideal use cases

• Retrofit aging motor control centers to restore performance and reliability without a full panel replacement
• OEM replacement for ongoing maintenance or part renewal in existing 11-300 configurations
• Custom MCC configurations where a higher-capacity bucket is needed within a standard 48" frame
• New installations that require proven compatibility with Eaton–Westinghouse 11-300 architecture

Practical insights for installation and operation

Before integrating, verify that the existing MCC setup matches the 11-300 series and that the 48" vertical frame aligns with your rails and bus connections. The 240 V three-phase supply supports typical motor loads found in industrial environments, helping you streamline controls and protection without overcomplicating the power distribution scheme. If you’re upgrading from a smaller bucket, this 300 A unit consolidates capacity within the same frame, potentially reducing panel footprint and simplifying wiring layouts.

In summary, the Eaton – Westinghouse 11-300 Breaker MCC Bucket from AmpState is a purpose-driven component for serious motor control and power distribution needs. It combines precise compatibility with tangible capacity benefits, enabling reliable upgrades, efficient retrofits, and scalable MCC configurations tailored to industrial settings.
