Eaton - Westinghouse 11-350 - Breaker MCC Bucket - 90 A, 480 V, 15" Height, 3 P | AmpState

Meet the Eaton - Westinghouse 11-350 Breaker MCC Bucket from AmpState—a purpose-built module designed to drop into your existing motor control center with precision. Rated for 90 A at 480 V in a three-phase 60 Hz system, this bucket is engineered to support mid-size motor control and power distribution tasks in demanding industrial and commercial environments. Its 15" vertical frame is purposefully matched to the 11-350 MCC footprint, making retrofit, OEM replacement, and custom MCC configurations straightforward and reliable.

Key advantages that matter in the field

• Exact compatibility with Eaton - Westinghouse 11-350 MCCs: Specifically designed as a Breaker MCC Bucket for the 11-350 frame, ensuring proper mounting, bus connections, and alignment with existing infrastructure.
• High-current performance for demanding motors: 90 A continuous rating at 480 V (three-phase, 60 Hz) supports larger or multiple motor loads without overstressing the switchgear.
• Compact, practical 15" height: A vertical footprint that fits standard MCC racks while leaving room for wiring, accessories, and future expansion.
• Versatile applications: retrofit, OEM replacement, and custom configurations: Perfect for upgrading aging MCCs, replacing worn components, or creating tailored MCC layouts to meet evolving plant needs.
• Industrial-ready construction for real-world environments: Built to withstand the rigors of commercial and industrial power distribution and motor control tasks.

Who will benefit

This bucket is ideal for facilities that rely on reliable, scalable motor control and power distribution—manufacturing floors, processing plants, packaging lines, facilities with heavy machinery, and service upgrades in warehouses or data centers. If you’re upgrading an 11-350 MCC or reconfiguring a control room to handle higher-current motors, this 90 A, 480 V bucket provides the right balance of capacity and fit.

Use cases and practical scenarios

• Retrofit an aging MCC to support higher-demand motors without a full switchgear replacement.
• Replace worn breakers and buckets in existing 11-350 frames to extend equipment life.
• Design custom MCC configurations for new lines or modular expansions, keeping the same trusted frame and interface.
• Upgrade to 480 V three-phase distribution to power larger pumps, conveyors, fans, or compressors with improved control and protection.

Why this bucket stands apart

Unlike generic MCC components, this Breaker MCC Bucket is purpose-built for the 11-350 frame, offering alignment with the exact mounting patterns and electrical interfaces your system relies on. The result is quicker install times, fewer fitment surprises, and a retrofit that preserves existing protections and control logic—all while enabling higher current handling in a familiar form factor.

Installation and best practices

• Verify that your MCC frame matches the 11-350 specification and that the 15" vertical bucket height aligns with your enclosure clearances.
• Coordinate with a qualified electrical technician to perform the retrofit or replacement, following lockout/tagout protocols and local codes.
• Inspect bus connections and lug interfaces during installation to ensure solid, low-resistance contact.
• Document part numbers and maintain OEM-compatible labeling for future maintenance and part sourcing.

Choose the Eaton - Westinghouse 11-350 Breaker MCC Bucket for reliable, OEM-aligned performance in 90 A, 480 V three-phase applications. It’s the practical upgrade your motor control center needs to sustain uptime, support scalable operations, and keep your distribution network running smoothly.
