Engineered for demanding industrial motor control environments, the Siemens Marq 21 Breaker MCC Bucket delivers a precise 90 A, 208 V, 3-Pole configuration that integrates flawlessly with Siemens Marq 21 MCC lineups. Designed for OEM replacement and retrofit projects, this bucket preserves the exact mounting footprint and electrical geometry you rely on, helping you minimize downtime and rework during upgrades or rebuilds.

• Current rating: 90 A
• Voltage: 208 V
• Configuration: 3-Pole breaker MCC bucket
• Bucket height: 15 inches
• Compatibility: Direct fit for Siemens Marq 21 MCC systems
• Application: Ideal for OEM replacement and retrofit initiatives in motor control centers

Why this bucket stands out in industrial setups: it’s built to integrate with the Marq 21 family’s electrical and mechanical layout, ensuring secure mounting, aligned bus connections, and consistent performance under load. By choosing an OEM Siemens bucket, you reduce the risk of misalignment or inconsistent contact quality that can occur with off-brand substitutes. AmpState backs this product with its worldwide supply of Siemens MCC components, enabling faster turnaround for maintenance teams and OEMs alike.

Ideal use scenarios

• Preventive maintenance cycles where a worn or obsolete MCC bucket needs a precise 90 A, 208 V replacement
• Retrofit projects upgrading aging motor control centers to current Siemens Marq 21 configurations
• OEM rebuilds in manufacturing lines that require consistent, field-proven components with exact fit and performance

What you’ll gain in daily operations

• Reliable 3-phase protection for medium-duty motors up to 90 A, reducing unplanned outages
• Streamlined installation with a known Siemens footprint, cutting commissioning time
• Consistent electrical characteristics across replaced buckets, helping maintain system balance

Practical tips for installation and maintenance: verify the Marq 21 frame compatibility before swapping, ensure the power is fully isolated (lockout/tagout), confirm the 208 V supply matches your distribution setup, and plan for proper wiring routing to maintain clean, short lead paths. When in doubt, rely on AmpState’s global network for OEM Siemens MCC components to support your retrofit timeline and long-term reliability.
