Engineered for demanding industrial motor control, the Siemens tiastar Breaker MCC Bucket delivers dependable power management in a compact 18" form tailored for 300 A, 480 V, 3-Pole configurations. Designed as a direct replacement for Siemens tiastar MCC systems, this bucket slides into place with minimal downtime, making it an ideal choice for retrofit projects and OEM replacements.
Common use scenarios include planned maintenance outages, capacity expansions within existing motor control centers, and retrofits that align older panels with current 480 V standards. This bucket provides a tidy, organized solution that helps keep critical equipment online when it matters most.
