Why this bucket matters for your MCC

• OEM‑matched compatibility with Eaton‑Westinghouse 11‑300 motor control centers ensures correct contact alignment, mounting holes, and engineering tolerances—minimizing installation guesswork and field adjustments.
• Designed for retrofit and expansion, it lets you refresh aging MCCs or add capacity without采购ing an entire cabinet. The 12" height footprint is optimized for tight spaces while preserving serviceability.
• Three‑phase, 480 V operation aligns with common industrial power distribution standards, making it suitable for a wide range of motors and equipment in manufacturing, processing, and facilities environments.
• As a purpose‑built MCC bucket, it streamlines spare parts management—keeping your maintenance schedule predictable and downtime minimal when replacements are needed.

Ideal use cases

• Retrofit projects where an existing Eaton-Westinghouse 11‑300 MCC requires a reliable 125 A, 480 V breaker bucket to restore or upgrade performance.
• OEM replacement scenarios to maintain the integrity of original designs and ensure continued compatibility with downstream accessories and controls.
• Custom MCC configurations, where modular buckets are needed to tailor motor control and distribution for specific load profiles and space constraints.
• Spare parts strategy for industrial maintenance teams seeking to minimize downtime during scheduled maintenance or unexpected outages.

Practical installation tips

• Confirm the bucket’s 12" vertical frame fits your current MCC enclosure’s tolerances and mounting provisions before ordering.
• Verify three‑phase 480 V compatibility with your motor and drive systems to ensure proper voltage and protection coordination.
• Plan for OEM replacement alignment to maintain consistent wiring diagrams and control circuits across the MCC lineup.
• Keep a matched set of spare MCC buckets on hand for rapid swaps during preventive maintenance programs.
