Eaton - Westinghouse 11-300 - Breaker MCC Bucket - 90 A, 208 V, 15" Height, 3 P | AmpState

Designed to slot directly into Eaton-Westinghouse 11-300 motor control centers, the 11-300 Breaker MCC Bucket from AmpState delivers dependable, industrial-grade power distribution for demanding environments. With a 90 A rating at 208 V, this unit is built for real-world motor control applications—protecting starters, feeders, and loads while keeping downtime to a minimum.

Why this MCC bucket stands out

• Exact compatibility with Eaton-Westinghouse 11-300 MCCs — engineered as a plug-in breaker bucket to ensure clean installation, reliable electrical connections, and streamlined maintenance within existing frameworks.
• 90 A at 208 V (Three-phase, 60 Hz) — capable of handling typical motor start-up and running currents in commercial and industrial plants without overloading the distribution path.
• 15" vertical frame height — compact footprint that fits into constrained electrical rooms, enabling efficient aisle space management and easier retrofits.
• Versatile use cases — ideal for retrofit projects, OEM replacements, and custom MCC configurations, giving engineers the flexibility to modernize or expand power control without rebuilding the entire switchgear lineup.
• Durable, purpose-built construction — designed for industrial environments where reliability and long service life matter, supporting steady operation across demanding production schedules.

What problems this solves

When upgrading aging motor control infrastructure or expanding capacity, compatibility and downtime are the biggest hurdles. This MCC bucket solves them by providing a drop-in replacement that aligns with the 11-300 ecosystem, reduces retrofit complexity, and preserves existing bus and mounting patterns. It supports consistent protection and distribution for motors, conveyors, pumps, fans, and other industrial loads powered from a 208 V three-phase supply.

Use cases and ideal customers

• Plant maintenance teams performing mid-life upgrades on existing MCCs—minimizing wiring changes and bus rework while improving reliability.
• OEM integrators building or expanding motor control configurations for manufacturing lines, packaging, processing, or material handling facilities.
• Retrofit projects where a proven 11-300 compatible bucket is the simplest path to restore or enhance motor control functionality.

How it compares to generic alternatives

Unlike generic MCC buckets, this unit is purpose-built for the Eaton-Westinghouse 11-300 family, ensuring precise fit, alignment, and electrical performance. It supports OEM replacement workflows and custom MCC configurations without requiring extensive reengineering, helping you preserve existing protective schemes and upstream electrical coordination.

Practical installation and care tips

• Verify the 11-300 compatibility and confirm mounting and bus connections match your current MCC layout.
• Plan for a minimal downtime window to swap in the bucket and re-check alignment with adjacent sections and feeders.
• Document the retrofit as part of your maintenance records, noting amperage, voltage, and phase configuration for future upgrades.
