Eaton - Westinghouse - Type W - Breaker MCC Bucket - 90 A, 480 V, 18" Height, 3 P | AmpState

Overview

The Eaton Type W Breaker MCC Bucket, 90 A at 480 V with a 3-Pole configuration, is engineered for demanding industrial motor control applications. Specifically designed to slot into Eaton Type W MCC systems, this unit serves as a precise direct replacement for OEM parts and retrofit projects, helping you maintain reliable protection and control across your motor circuits. At 18 inches in height, it fits standard MCC enclosures while delivering robust performance for high-demand environments.

Key Specifications

• Brand: Eaton
• Model/Configuration: Type W Breaker MCC Bucket, 3-Pole
• Rating: 90 A, 480 V
• Height: 18 inches
• Compatibility: Fits Eaton Type W MCC systems; works as a direct OEM replacement and for retrofit installations

Why this MCC Bucket Stands Out

• Exact-fit compatibility: Designed to drop into existing Eaton Type W motor control centers without modifications, preserving wiring layouts, bus connections, and protective coordination.
• Reliability for demanding loads: The 90 A, 480 V rating supports medium-to-large motor loads common in manufacturing, pumping, and processing facilities, while preserving coordinated protection and safe shutdown.
• Seamless replacements: As a true direct replacement, it minimizes downtime during maintenance or upgrades and reduces the risk of mismatched parts.
• Proven architecture: Built to endure industrial environments, maintaining consistent performance across cycles and temperature variations typical of MCC applications.
• Global delivery: AmpState provides reliable, worldwide shipping so you can source this essential component wherever your facility is located.

Ideal Use Cases

• Retrofits of aging or failed Type W MCC buckets in existing facilities to restore motor control reliability quickly.
• New or upgraded motor control centers that utilize Eaton Type W hardware for standardized protection schemes.
• Industrial plants with mid-to-high current motor loads that require a robust, easily replaceable 3-pole breaker bucket at 480 V.

Installation Considerations and Tips

• Verify mechanical fit and electrical compatibility with your current Eaton Type W MCC assembly before installation.
• Ensure correct alignment with busbars and mounting hardware to preserve proper contact resistance and protection coordination.
• Use only trained personnel for replacement to maintain safety and ensure proper locking and labeling of circuits.
• Keep spare MCC buckets on hand as part of a proactive maintenance strategy to minimize downtime in critical lines.

What You Gain

• Consistent protection for motor circuits with predictable, maintainable performance.
• Reduced downtime thanks to a straightforward, direct-fit replacement approach common in OEM and retrofit scenarios.
• Confidence in sourcing from AmpState, with global delivery options and a focus on supplying dependable MCC components.
