Eaton Westinghouse 11-300 400A Breaker MCC Bucket 208V 3P

The Eaton - Westinghouse 11-300 Breaker MCC Bucket is a purpose-built module designed to slot into 11-300 motor control centers. With a 400 A rating at 208 V and a 36" tall vertical frame, this bucket is engineered to support demanding industrial power distribution and motor control tasks with confidence.

• High-current capability: 400 A continuous at 208 V three-phase (60 Hz) to handle large motor loads and demanding workflows.
• Optimal sizing for MCCs: 36" vertical frame fits standard Eaton-Westinghouse 11-300 configurations, enabling clean retrofits and streamlined OEM replacements.
• Designed for retrofit and OEM replacement: Specifically engineered to drop into existing MCC housings or be integrated into custom MCC configurations without extensive rewiring.
• Reliable motor control distribution: Built for industrial environments where stable power distribution and quick maintenance are priorities.
• 3-pole (3P) operation: Suited for three-phase power systems, ensuring balanced loads and consistent performance in industrial plants.

Why this MCC bucket matters for your operation

Upgrading or replacing components in a motor control center doesn’t have to mean downtime or complicated sourcing. The Eaton-Westinghouse 11-300 Breaker MCC Bucket offers a precise fit for Retrofit, OEM replacement, and customized MCC configurations, reducing installation time and preserving control architecture. Its 400 A at 208 V rating aligns with common industrial feeders and motor starters, letting you consolidate power distribution without overhauling your switchgear layout.

Ideal use scenarios

• Modernizing aging MCCs to improve reliability and expand capacity on production lines, pumping stations, or HVAC systems.
• OEM replacement in plants that rely on Eaton-Westinghouse 11-300 frame families, ensuring compatibility with existing control logic and interlocks.
• Custom MCC configurations where a 36" tall, 3-pole bucket is required to fit strict panel dimensions and wiring schemes.
• Retrofit projects aiming to minimize downtime by swapping like-for-like modules rather than full switchgear rewrites.
