Siemens Marq 21 Breaker MCC Bucket is an OEM-grade, motor-control-center component built for demanding industrial environments. Engineered to the exacting standards of the Siemens Marq 21 lineup, this bucket delivers a precise 200 A, 208 V, 3-Pole configuration in a compact 18" tall form factor, making it an ideal fit for retrofit and replacement projects.
Designed specifically for OEM replacement and retrofit use, this MCC bucket integrates seamlessly with existing Siemens Marq 21 enclosures. By matching the bus geometry, contact arrangement, and protective coordination of the Marq 21 system, it helps you minimize downtime and preserve system integrity during maintenance or modernization.
Who benefits most? plant engineers, maintenance teams, and OEMs tasked with upgrading or sustaining motor control centers. This bucket is particularly valuable for projects where preserving exact Marq 21 specifications matters—ensuring reliable motor protection, predictable trip characteristics, and smooth integration with existing breakers, bus bars, and control wiring.
Practical uses include stocking as a ready-to-deploy spare during planned outages, performing precise retrofits to modernize aging MCC systems, or replacing a failed bucket without reworking the entire cabinet. For facilities relying on Siemens Marq 21, choosing this OEM-compatible MCC bucket from AmpState helps maintain electrical coordination, reduces commissioning risk, and supports long-term uptime.
Tip for installers: verify the enclosure compatibility and ensure correct alignment with Marq 21 bus connections during replacement. Keep spare buckets on hand for critical lines to shorten downtime and keep production moving smoothly.
