Why this MCC bucket stands out

What makes this breaker bucket unique is its precise compatibility with the 11-300 family, paired with a thoughtful vertical design that optimizes space in compact switchgear layouts. The 225 A rating at 480 V positions it as a strong choice for medium-to-large motor loads, giving you ample headroom for startup surges and continuous operation. Its rugged construction is built to withstand industrial environments, helping minimize downtime and maintenance needs in demanding facilities.

Practical use cases

• Upgrade aging MCCs to modern, compatible 11-300 buckets without rewiring the entire cabinet. The 18" vertical frame ensures alignment with existing bus bars and mounting hardware.
• When original buckets reach end-of-life, swap to a direct-fit 11-300 breaker bucket to maintain performance and service continuity.
• Build tailored motor control centers that meet specific circuit-counts and load profiles—this bucket provides reliable, scalable performance within a modular MCC design.
• Supports heavy motor loads in manufacturing, processing, and facility infrastructure where consistent 3-phase power delivery is critical.

How it benefits your operation

By aligning with standard 11-300 MCC footprints, this bucket reduces installation complexity and parts fragmentation. The 225 A, 480 V capacity delivers dependable current handling for motor starters, contactors, and related protective devices, helping you manage inrush, overload protection, and safe isolation without compromising performance. The 18" height preserves cabinet clearance and allows straightforward integration with existing wiring and bus connections.

Tips for installation and lifecycle

Before integrating this MCC bucket, verify physical fit within your motor control center and confirm compatibility with your bus bars and protective device arrays. Plan for alignment with downstream protection schemes and ensure proper torque on mounting screws to maintain electrical integrity. Keep spare buckets on hand to streamline future replacements and minimize downtime during maintenance windows.
