Eaton - Westinghouse 11-300 - Breaker MCC Bucket - 300 A, 240 V, 42" Height, 3 P | AmpState

Engineered to handle demanding industrial motor control tasks, the Eaton - Westinghouse 11-300 Breaker MCC Bucket (300 A, 240 V) is a purpose-built module designed to drop seamlessly into Eaton Westinghouse 11-300 motor control centers. With a 42" vertical frame, it aligns perfectly with standard MCC bays, delivering reliable power distribution for commercial and industrial environments.

• Amp rating and voltage: 300 A at 240 V (three-phase, 60 Hz) for robust motor start-up and continuous operation.
• Frame height and footprint: 42" vertical frame to match common MCC configurations and maintain consistent enclosure alignment.
• Configuration: 3-pole breaker MCC bucket—built to support three-phase motor control circuits.
• Application and compatibility: Designed specifically for use with Eaton - Westinghouse 11-300 motor control centers; ideal for retrofit projects, OEM replacements, and custom MCC configurations.

Why this MCC bucket stands out: it’s not just a drop-in replacement—it’s a calculated upgrade path for facilities that rely on stable, scalable motor control. The combination of 300 A capacity and 240 V three-phase compatibility ensures compatibility with a wide range of industrial motors and drives, while the 42" frame height preserves existing bus connections and enclosure spacing. This makes planned upgrades, expansions, and rebuilds faster and less disruptive.

Who benefits most

Facilities with aging MCC infrastructure, manufacturers planning capacity additions, and service teams performing OEM replacements will find this bucket a practical, long-term solution. It’s particularly well-suited for environments where uptime matters and standardization across motor control centers reduces maintenance complexity.

Practical considerations and tips

Before installation, verify that the 11-300 architecture in your MCC matches the bucket’s specifications (300 A, 240 V, 42" frame, 3 P). Plan for proper mounting, bus bar alignment, and compatible interlocks to ensure a smooth retrofit or replacement. This MCC bucket is designed to integrate with existing control logic and protection schemes, helping maintain consistent motor protection and distribution across your facility.

Equip your power distribution system with a trusted, purpose-built MCC bucket from AmpState—the reliable choice for Eaton Westinghouse 11-300 installations, retrofit projects, and OEM replacements that keep industrial operations flowing.
