Eaton Westinghouse 11-300 100A 600V MCC Bucket 3P 42

Meet the Eaton - Westinghouse 11-300 Breaker MCC Bucket from AmpState — a purpose-built module designed to snugly slot into your existing motor control center with precision and enduring reliability. This MCC bucket is engineered for industrial environments where dependable power distribution and motor control are non-negotiable.

With a 100 A rating at 600 V (three-phase, 60 Hz), this 42" tall, 3‑pole breaker bucket delivers solid, scalable performance for demanding applications. It’s not just a drop-in part; it’s a strategic upgrade that helps you optimize space, streamline maintenance, and extend the life of your MCC investment.

Why this MCC bucket stands out

• Exact compatibility with Eaton-Westinghouse 11-300 MCC chassis — identical mounting patterns and electrical interfaces facilitate seamless retrofits, OEM replacements, and custom MCC configurations without invasive panel work.
• Compact, high‑capacity frame — a 42" vertical frame supports robust motor control layouts while preserving rack space for additional breakers or accessories.
• Solid electrical performance — designed for 100 A continuous operation at up to 600 V, enabling reliable distribution for moderate to large industrial loads.
• Versatile use scenarios — ideal for retrofit projects, OEM replacement programs, and custom MCC builds where reliable, field-proven components are essential.

Ideal for who and where

• Maintenance engineers upgrading aging motor control centers in manufacturing facilities, processing plants, and large commercial sites.
• OEM integrators developing new line configurations that require compatible MCC buckets for Eaton-Westinghouse 11-300 systems.
• Electrical contractors conducting plant expansions or retrofit projects that demand credible, plug‑and‑play replaceable parts with predictable performance.

Practical considerations and best practices

• Ensure the existing MCC chassis is compatible with the 11-300 bucket interface to minimize retrofit complexity.
• Plan for three‑phase, 600 V service when integrating this bucket to maintain proper phase balance and protective coordination.
• Verify installation clearances around the 42" frame to accommodate wiring access and future maintenance.
• Consult your AmpState technical support for pairing recommendations with your specific motor loads and protection schemes.
