High interrupt rating of 85 kAIC provides robust fault clearing, reducing the risk of cascading outages in demanding fault conditions and enabling safer, faster system restoration in industrial environments. The 6000 A Iu rating supports extensive load demands, allowing you to protect large power distribution panels without frequent component upgrades, which translates to lower total cost of ownership and improved uptime in manufacturing facilities and data centers. A drawout vertical design with motorized racking simplifies maintenance and line isolation, cutting downtime during replacement or servicing and improving technician safety in retrofit projects and new builds. The PXR20 LSI trip unit delivers advanced protection logic and selective coordination, helping you tailor settings for critical loads while minimizing nuisance trips across mixed loads and motor start-ups. UL Listed, CE Marked, and CSA Certified compliance simplifies procurement and accelerates commissioning, while NEMA compatibility ensures rugged operation in harsh industrial environments. Together with Magnum’s double standard frame and three-pole configuration, this breaker provides scalable protection for control panels, switchgear, and motor control centers, with Power Xpert Protection Manager compatibility for integrated monitoring and analytics.

FAQs
The MPS8603MEAXX2A features a drawout vertical design with motorized racking, compatible with Magnum PXR frames and standard double-frame switchgear. It simplifies mounting in new builds and retrofit projects by preserving existing panel footprints while providing a secure, safe disconnect during maintenance.
Key specs include three poles, rated uninterrupted current (Iu) of 6000 A, and an interrupt rating of 85 kAIC. The unit uses a PXR20 LSI trip unit to deliver precise protection and selectable coordination for critical loads in harsh industrial environments.
Yes. With 6000 A Iu capacity and 85 kAIC interrupt rating, three-pole configuration, and a rugged drawout design, it is well-suited for data centers, process plants, and heavy manufacturing where reliable protection and fast fault clearance are essential.
The unit is UL Listed, CE Marked, and CSA Certified, with additional compliance including NEMA. This broad certification footprint reduces regulatory risk and simplifies cross-border procurement for global projects.
Motorized racking enables quicker, safer line isolation and faster breaker replacements, reducing maintenance downtime and service windows. When combined with selective coordination from the PXR20 LSI unit, it also minimizes unnecessary outages, improving overall equipment effectiveness (OEE) and project ROI.
