Siemens - Marq 21 - Breaker MCC Bucket - 400 A, 208 V, 48" Height, 3 P | AmpState

Siemens - Marq 21 Breaker MCC Bucket delivers reliable, factory-grade motor control for industrial environments where durability and exact compatibility matter. Designed specifically for the Siemens Marq 21 MCC lineup, this 400 A, 208 V, 3-Pole breaker bucket with a 48" height is built for OEM replacement and retrofit projects, helping you minimize downtime and preserve system performance.

Optimized for Siemens Marq 21 MCC Systems

Engineered to drop directly into existing Marq 21 assemblies, this MCC bucket preserves the integrity of your motor control center while delivering trusted Siemens performance. Its precise 3-Pole configuration and standard 48" bucket height streamline installation, so you can service or upgrade without extensive enclosure modifications.

• Rating: 400 A
• Voltage: 208 V
• Poles: 3-Pole
• Bucket height: 48 inches
• Series: Marq 21
• Configuration: Breaker MCC Bucket

Why This MCC Bucket Stands Out

• OEM-ready and retrofit-friendly: Seamlessly replaces aging components or integrates into new builds that require Siemens Marq 21 compatibility, minimizing wiring changes and enclosure adaptations.
• Manufacturer-aligned performance: Built to mirror Siemens’ original specifications for reliable protection and control of heavy-duty motor loads in industrial settings.
• Global supply endorsement: AmpState sources authentic Siemens MCC components, supporting worldwide projects with genuine parts and verified compatibility.

Ideal Use Cases

• Factory floor upgrades where existing Marq 21 MCC buckets are approaching end-of-life and you need a dependable, drop-in replacement.
• OEM equipment refreshes in turnkey manufacturing lines that demand consistent Siemens-compatible motor control performance.
• Retrofits aimed at preserving current wiring schemas while upgrading to a robust 400 A, 208 V, 3-Pole configuration for higher motor starting capability and protection.

What Problems It Solves

With its precise 400 A rating and 208 V operation, this bucket handles demanding motor start and run profiles without compromising enclosure geometry. Its Marq 21 compatibility minimizes field modification, reduces installation risk, and helps facilities maintain uptime during maintenance windows or retrofits.

Practical Tips for Use

• Confirm enclosure compatibility with the 48" bucket height to ensure a clean, secure fit in your existing Marq 21 system.
• Verify 3-Pole alignment in your MCC to avoid mis-wiring during replacement or retrofit.
• Coordinate with AmpState for authentic Siemens components and to validate any system-wide compatibility notes before procurement.

Choose the Siemens Marq 21 Breaker MCC Bucket when you need a purpose-built, OEM-grade solution that aligns with your existing Siemens motor control architecture. It’s the reliable, compatible path for upgrades, replacements, and long-term system performance in industrial environments.
