Siemens - Marq 21 - Breaker MCC Bucket - 125 A, 600 V, 36" Height, 3 P | AmpState

Siemens Marq 21 Breaker MCC Bucket — 125 A, 600 V, 3-Pole, 36" tall, 3 P Engineered for industrial motor control applications, this Breaker MCC Bucket is designed to slot seamlessly into Siemens Marq 21 MCC lineups. With a 125 A, 600 V, 3-Pole rating and a 36" bucket height, it provides a robust, drop-in solution for OEM replacement and retrofit projects, helping you maintain reliable power distribution in demanding environments.

• Exact specifications in one ready-to-install unit: 125 A, 600 V, 3-Pole configuration aligns with standard Marq 21 architectures.
• 36" bucket height fits conventional Siemens MCC enclosures, reducing alignment and mounting adjustments during retrofits.
• OEM replacement compatibility: engineered to integrate with existing Marq 21 setups, minimizing downtime and spare-part uncertainty.
• Retrofit-ready for upgrades: ideal for facilities upgrading capacity or replacing aging MCC components without overhauling the entire cabinet.
• Durable construction for industrial use: built to withstand demanding motor control tasks and continuous operation in harsh environments.

Why this bucket stands out

Unlike generic MCC buckets, this Siemens Marq 21 Breaker MCC Bucket is purpose-built for the Marq 21 platform. It delivers precise mounting interfaces, electrical characteristics, and physical dimensions compatible with Siemens’ ecosystem, which translates to fewer field adjustments, faster installation, and improved system reliability. The 3-Pole design supports balanced phase distribution, contributing to safer switching and reduced electrical stress in high-demand motor control applications.

Ideal use cases

• OEM installations needing authentic Siemens components that match Marq 21 specifications.
• Retrofits of aging MCCs where 125 A, 600 V protection and 3-Pole control are required.
• Facilities upgrading motor control capacity within existing Marq 21 enclosures without extensive cabinet redesign.
• Service and maintenance projects that prioritize exact-fit replacements to minimize downtime.

Practical considerations and best practices

Ensure the enclosure and mounting interface are compatible with the 36" bucket height and the 3-Pole configuration. Schedule downtime for safe replacement, verify electrical ratings match your system load requirements, and plan for proper interconnection with the existing bus and breaker assemblies. When in doubt, rely on Siemens-spec parts to preserve warranty integrity and maintain consistent performance across your motor control center.
