Engineered for reliable power distribution in demanding industrial environments, the Eaton - Westinghouse 11-300 Breaker MCC Bucket from AmpState delivers a precise, ready-to-retrofit solution for 11-300 motor control centers. With a 100 A rating at 600 V and a compact 18" vertical frame, this breaker MCC bucket is built to keep large motor loads under safe control while fitting neatly into established Eaton Westinghouse MCC configurations.

Designed for seamless compatibility

• Fits 11-300 MCC systems — specifically engineered to pair with Eaton - Westinghouse 11-300 motor control centers for plug-and-play replacement and consistent performance.
• 18" vertical frame — optimized height to maximize space in existing enclosures without compromising accessibility or serviceability.
• 3-pole configuration — ideal for typical three-phase motor control and power distribution applications common in industrial facilities.
• 100 A at 600 V (three-phase, 60 Hz) — provides reliable switching and protection for medium-scale motors and associated equipment.

Key benefits that matter in the real world

• Retrofit-ready and OEM replacement — streamline upgrades, refurbishments, or phased expansions by swapping in a bucket that aligns with your existing MCC layout and electrical characteristics.
• Custom MCC configurations — accommodates tailored arrangements within your motor control center, enabling you to adapt to changing load profiles or control schemes.
• Industrial-grade performance — built to stand up to the rigors of continuous operation in manufacturing, processing, and commercial power distribution environments.
• Reliable motor control and distribution — a purpose-built component that helps ensure safe starting, protection, and control of large motors and associated circuits.

Ideal use cases

• Retrofit projects where legacy MCC buckets are aging or out of spec, requiring a precise 11-300-compatible replacement.
• OEM replacement initiatives to restore original performance and compatibility within existing equipment footprints.
• Custom MCC configurations for facilities expanding production lines or reconfiguring motor loads.
• Industrial power distribution setups that demand dependable, centralized motor control in one rugged, standardized module.

Practical installation and usage tips

• Verify that your MCC frame and bus connections align with the 18" vertical bucket dimensions and 3-pole, 600 V rating to ensure a clean, secure fit.
• Plan retrofit work during planned maintenance windows to minimize downtime and ensure safe, lockout/tagout procedures.
• Document the load profiles and motor classifications served by the bucket to optimize future expansions or replacements.
• Use as part of a broader strategy for standardized, modular MCC configurations to simplify stocking and maintenance across facilities.
