Eaton - Westinghouse 11-300 - Breaker MCC Bucket - 250 A, 480 V, 48" Height, 3 P | AmpState

The Eaton - Westinghouse 11-300 Breaker MCC Bucket is purpose-built to slot into 11-300 motor control centers, delivering reliable power distribution for demanding industrial environments. With a 250 A rating at 480 V three-phase (60 Hz) and a full-height 48" vertical frame, this bucket is engineered for steady performance, easy retrofit, and scalable MCC configurations.

• Amp rating and voltage: 250 A at 480 V three-phase, 60 Hz, making it suitable for a wide range of motor control and distribution tasks.
• Frame and fit: 48" tall vertical frame designed to align with standard MCC rack dimensions, enabling straightforward integration into existing installations.
• 3-pole configuration: Built as a three-pole breaker MCC bucket to support common industrial motor circuits and control schemes.
• Designed for retrofit and OEM replacement: Specifically intended for retrofitting older centers, OEM upgrades, and custom MCC configurations without overhauling surrounding infrastructure.
• Application scope: Ideal for industrial motor control, power distribution, and facilities upgrading where reliability and modularity matter.

Why this bucket stands out in real-world setups:

Seamless compatibility with 11-300 frames means you can upgrade or refurbish your control center without reconfiguring buswork or field wiring. The 48" vertical footprint fits established plant layouts, reducing the need for costly realignments during replacements or upgrades. This makes it an economical choice for plants looking to extend the life of aging MCCs or standardize new modules across multiple lines.

Concrete benefits for operations include minimized downtime during swaps, predictable electrical characteristics across replacements, and the ability to tailor MCC configurations to changing motor loads. Whether you’re expanding your automation footprint, consolidating control sections, or refreshing an aging motor drive block, this bucket provides a solid, durable foundation.

Ideal use cases

• Retrofits in existing facilities where 11-300 MCCs are in use, enabling modernized protection and control without a full center replacement.
• OEM replacements in manufacturing lines, packaging systems, and process equipment where consistent performance and form factor matter.
• New MCC configurations for plants expanding motor loads or reconfiguring line layouts, with a trusted 250 A at 480 V three-phase capability.
• Industrial power distribution upgrades in facilities like water treatment, HVAC plants, conveyors, and pumps where reliable motor control is critical.

Practical guidance for deployment — confirm the 48" frame matches your current MCC height and that your system operates on 480 V, three-phase power. Use this bucket to standardize replacements across multiple centers, which simplifies maintenance, spare-part inventories, and technician training. When integrating, plan for consistent feeder sizing and protection coordination to maximize the benefits of modular MCC configurations.

In summary, the Eaton - Westinghouse 11-300 Breaker MCC Bucket is a purpose-built, retrofit-ready module that pairs a robust 250 A, 480 V three-phase specification with a 48" vertical frame, delivering reliable motor control and scalable power distribution. It’s the practical choice for facilities optimizing downtime, modernization, and consistency across industrial MCCs—without sacrificing performance or configurability.
