• 3-pole architecture for solid switching: Designed to support dependable motor control and protection in compact MCC layouts.

Ideal use cases

• Plant modernization projects where CENTERLINE 2100 MCCs require an upgraded breaker bucket without replacing the entire cabinet.
• OEM replacement scenarios that demand exact form, fit, and electrical compatibility to minimize downtime.
• New custom MCC configurations that need a reliable 300 A, 480 V solution within a compact vertical frame.
• Industrial facilities with space constraints but high-demand motor control needs, such as conveyors, compressors, processing lines, and HVAC systems.

Practical benefits and real-world performance

By aligning with the CENTERLINE 2100 platform, this MCC bucket delivers predictable electrical performance and streamlined maintenance. The 300 A rating at 480 V supports a broad range of motor starting and distribution scenarios, helping facilities optimize startup sequences and reduce voltage-related stress on drives and motors. The 12" height enables flexible bench-to-panel planning, letting engineers retrofit or expand without reconfiguring entire switchgear rows.

In environments where downtime is costly, the ability to perform OEM-compatible replacements or quick retrofits can shorten project timelines and improve system uptime. The Breaker MCC Bucket is built with industrial durability in mind, designed to withstand the demands of busy distribution racks while maintaining clean electrical separation and straightforward installability.

Installation, compatibility, and care

Designed for straightforward integration with CENTERLINE 2100 motor control centers, this bucket slots into existing vertical channels and aligns with standard 480 V three-phase motor control logic. When replacing older or incompatible components, clients can expect a smoother transition thanks to OEM-aligned form factors and mounting footprints.

Routine checks should focus on ensuring secure mounting, clean terminals, and proper clearance for cooling around the bucket. Given its role in critical motor control, verify compatibility with downstream protection devices and control circuits in your specific MCC configuration.
