Eaton - Westinghouse 11-300 - Breaker MCC Bucket - 100 A, 208 V, 30" Height, 3 P | AmpState

Meet the Eaton-Westinghouse 11-300 Breaker MCC Bucket—a purpose-built, 100 A module designed to slot into Eaton Westinghouse 11-300 motor control centers. This 3-pole breaker bucket is crafted to meet the demands of industrial and commercial power distribution, delivering reliable control for motors and line-side circuits while supporting retrofit, OEM replacement, and custom MCC configurations.

Why this MCC bucket stands out

• Direct compatibility with Eaton-Westinghouse 11-300 MCCs. A precise fitment that simplifies upgrades, reduces downtime, and preserves your existing control architecture.
• 100 A rating at 208 V (three-phase, 60 Hz). Suited for common industrial motor loads and distribution circuits without overbuilding the system.
• 30" vertical frame. Optimized for retrofit projects and OEM replacement within standard MCC enclosures, enabling clean, predictable installation in existing racks.
• 3-pole configuration. Handles typical three-phase motor control applications with dependable, balanced performance.
• Modular, serviceable design. Built for retrofit work and modular MCC configurations, helping you tailor power distribution as motor loads evolve.

Applications and use cases

Ideal for industrial facilities, manufacturing lines, and commercial power systems that rely on reliable motor control. Use this bucket when upgrading aging MCC components, replacing a failed module, or building a customized MCC bank that aligns with 11-300 architecture. Its compatibility and frame sizing make it a practical choice for projects focused on continuity of operation and ease of maintenance.

What problems it solves

• Reduces downtime during retrofits by offering a ready-to-install bucket that matches existing 11-300 configurations.
• Provides a clear path for OEM replacements, ensuring long-term compatibility and spare-part availability.
• Supports scalable motor control setups, enabling engineers to expand or reconfigure MCC layouts without major reinterpretation of the control scheme.
