Eaton - Westinghouse 11-350 - Breaker MCC Bucket - 20 A, 480 V, 18" Height, 3 P | AmpState

Engineered for rugged industrial duty, the Eaton-Westinghouse 11-350 Breaker MCC Bucket is a purpose-built module designed to integrate seamlessly with Eaton – Westinghouse 11-350 motor control centers. With a 20 A, 480 V (three-phase, 60 Hz) rating and an 18" vertical frame, this bucket is built to handle demanding motor control and power distribution needs in manufacturing, processing, and commercial facilities.

Why this Breaker MCC Bucket stands out

• Exact fit for 11-350 frames: Precision engineering ensures proper alignment with bus bars and mounting points, enabling quick, plug-and-play installation in retrofit, OEM replacement, or custom MCC configurations.
• Specific electrical rating: 20 A at 480 V across three phases supports common motor loads such as conveyors, pumps, fans, and small drives, delivering reliable protection and control.
• Compact, compatible footprint: An 18" vertical frame optimizes space within mid- to large-scale MCC assemblies while leaving room for wiring and terminal blocks.
• Three-pole design (3P): Simplifies protection coordination and ensures balanced distribution across phases, which is essential for motor start-up and load sharing.
• Retrofit-friendly and OEM-ready: Ideal for upgrading aging MCCs, replacing worn buckets, or building customized motor control solutions without re-engineering the cabinet interior.
• Rugged for industrial environments: Built to withstand the vibrations, dust, and temperature variations typical of industrial plants, helping to minimize maintenance and downtime.

Practical use cases

• Upgrading legacy 11-350 MCC installations to restore reliable motor control in facilities with conveyors, pumping stations, or ventilation systems.
• OEM replacement projects where matching hardware speeds up assembly and reduces installation risk.
• Custom MCC configurations for new lines or plant expansions that require a proven 3P, 480 V protection bucket integrated into an existing frame.
• Repair and maintenance programs that aim to standardize components across multiple plants for easier stocking and procurement.
