Introducing the Siemens Marq 21 Breaker MCC Bucket — a purpose-built solution for industrial motor control panels that demand precise compatibility and reliable protection. Engineered to plug into Siemens Marq 21 MCC lineups, this 6" tall bucket delivers a clean, OEM-grade fit for 40 A, 208 V, 3-Pole applications. Designed for OEM replacement and retrofit projects, it helps you maintain panel integrity while upgrading or restoring motor protection without the hassle of custom fabrication.
Motor control centers are cornerstone infrastructure for production lines, pumps, compressors, and conveyors. When a bucket reaches end-of-life or you’re upgrading panel capacity, using the genuine Siemens Marq 21 Breaker MCC Bucket ensures that protection curves, trip settings, and mechanical interfaces stay consistent with the rest of the MCC. The 40 A rating covers a broad range of standard industrial motors, helping to protect against overloads while allowing reliable starting and operation in a 208 V three-phase system.
Choose the Siemens Marq 21 Breaker MCC Bucket for a precise, reliable replacement that preserves the electrical harmony of your motor control center. A smart choice for OEM compatibility, retrofit projects, and ongoing plant uptime.
