Engineered for 300 A at 240 V in a 3‑pole configuration, this bucket powers demanding applications with steady, predictable protection and control in tough environments.
Designed for Siemens Marq 21 MCC lineups, it serves as an exact OEM replacement and retrofit option—minimizing downtime and simplifying upgrades in existing cabinets.
