Siemens - Marq 21 - Breaker MCC Bucket - 5 A, 208 V, 12" Height, 3 P | AmpState

The Siemens Marq 21 Breaker MCC Bucket, rated 5 A at 208 V and configured for 3 poles, is a purpose-built OEM component for industrial motor control. Designed to fit seamlessly within Siemens Marq 21 MCC panels, this bucket delivers reliable protection and streamlined serviceability for demanding applications where uptime and precision matter.

• Configuration: Breaker MCC Bucket, 3-Pole
• Electrical rating: 5 A, 208 V
• Physical size: 12" bucket height for a precise, space-conscious fit
• Compatibility: Specifically engineered for Siemens Marq 21 MCC lineups
• Applications: Ideal for OEM replacement and retrofit projects in existing Marq 21 installations

Why this bucket stands out in real-world motor control environments. For facilities running heavy-duty conveyors, pumps, fans, or processing machinery, replacing a worn or incompatible MCC bucket with a genuine Siemens Marq 21 unit ensures coordinated protection and predictable behavior across the control circuit. The 5 A, 208 V, 3-Pole configuration aligns with common motor starter and protection schemes, helping to preserve protective relays, interlocks, and the overall fault-response profile of your MCC panel.

Key advantages that matter on the shop floor

• Genuine fit, genuine performance: As part of the Siemens Marq 21 family, this bucket preserves the electrical geometry, contact alignment, and mounting patterns your panel was designed to accept, reducing installation guesswork and the need for adapters.
• OEM replacement confidence: Engineered for retrofit and OEM replacement scenarios, so downtime is minimized and consistency with existing protection schemes is maintained.
• Space-efficient, purpose-built design: The 12" bucket height is matched to typical Marq 21 footprints, helping you maintain cabinet clearances and wiring routing without surprises.
• Versatile for multiple applications: Suitable for a range of industrial motor loads up to 5 A per pole, making it a practical choice for new builds or capacity expansions that rely on standardized Siemens components.

Ideal scenarios and use cases

• OEM replacements during scheduled maintenance to preserve panel integrity and protection coordination.
• Retrofit projects where upgrading to Marq 21 MCC architecture is part of a modernization effort.
• Repairs or expansions in facilities with existing Siemens Marq 21 systems needing a like-for-like MCC bucket to ensure consistent performance.
• Applications involving compact motor control assemblies where space constraints require a precise 12" bucket profile.
