Eaton - Cutler Hammer Freedom Unitrol - Breaker MCC Bucket - 225 A, 480 V, 18" Height, 3 P | AmpState

Designed for industrial motor control centers, the Eaton - Cutler Hammer Freedom Unitrol Breaker MCC Bucket is a purpose-built 225 A, 480 V, 3-Pole module that slots neatly into Freedom Unitrol assemblies. This is not a generic replacement—it's a direct-fit, retrofit-ready bucket engineered to match Eaton's original specifications for reliable performance and ongoing serviceability.

Key features include a robust 225 A rating at 480 V, a 3-Pole arrangement for three-phase protection, and an 18" bucket height that aligns with standard Unitrol bays. This ensures a snug, plug-and-play fit that minimizes wiring changes and downtime during upgrade or service cycles.

What makes this MCC bucket stand out

Exact form-fit and electrical compatibility: Built to complement the Eaton - Cutler Hammer Freedom Unitrol line, this bucket preserves the original bus connections, mounting pattern, and interface points, reducing retrofit risk and installation time.

Reliable protection for demanding loads: As a Breaker MCC Bucket, it consolidates protection and control in a compact module suitable for large motors, pumps, conveyors, and industrial equipment operating at 480 V three-phase power.

Flexible retrofit or direct replacement: Use it as a replacement for aging buckets or as part of a controlled modernization plan for motor control centers, enabling consistent protection without overhauling surrounding infrastructure.

Ideal use cases and environments

Factories, batch processing plants, packaging lines, and material handling operations that rely on heavy motors can benefit from this module. The 225 A, 480 V rating handles high-inrush events common in startup sequences, while the three-pole configuration provides balanced protection across phases.

This MCC bucket is also a practical retrofit option when upgrading older Unitrol cabinets to maintain compatibility with existing breakers, wiring schemes, and control wiring harnesses, preserving downtime windows and field labor costs.
