Why choose this MCC bucket?

Durability and compatibility are at the core. The bucket is engineered to glide into existing 11-350 frames, aligning with the MCC's bus and accessories for quick installation. The 24" vertical format is optimized for spaces where ceiling height or rack length is a constraint, while still offering ample clearance for wiring, accessories, and serviceability.

Use cases and ideal customers

• Retrofit old or undersized MCCs with a proven 125 A, 480 V bucket to restore capacity and improve reliability on motor loads such as conveyors, pumps, fans, and processing equipment.
• OEM replacement for manufacturers updating plant-wide MCC footprints without swapping entire panels.
• Customization scenarios where modular MCC configurations require a compatible, high-availability breaker bucket that fits standard 11-350 hardware.

Performance and reliability you can trust

With three-pole design, the bucket supports balanced, three-phase motor control essential for smooth starts, soft-start capable systems, and coordinated protection. Using OEM-grade components minimizes downtime and ensures consistent trip characteristics, easing maintenance and diagnostics across the facility.

Practical tips for installation and care

• Verify mounting alignment with the 11-350 chassis before seating the bucket to prevent misalignment of bus connections.
• Ensure proper torque on mounting hardware and verify busbar contact surfaces are clean and free of oxidation for reliable connectivity.
• During retrofit, sequence the installation to minimize panel downtime—insert the bucket, connect control wiring, then perform a controlled power-up sequence with appropriate fusing and protection settings as per your MCC guidelines.

If you’re stocking and deploying mid-range MCCs, the Eaton - Westinghouse 11-350 Breaker MCC Bucket (125 A, 480 V, 24" height, 3 P) is a precise, durable choice that keeps motor control centralized and dependable.
