FAQs

The MPSC503MEAXX2F uses a drawout vertical mounting approach with a motorized racking system, compatible with Magnum PXR frames and three-pole configurations. Ensure panel space accommodates a double standard frame up to 31.1 in wide and 16.3 in deep, with proper bus connections and torque per Eaton guidance. Verify LSIG ARMS trip module compatibility and confirm panel clearance for maintenance.
Key ratings include rated uninterrupted current Iu = 5000 A and an interrupt rating of 100 kAIC, with a three-pole, drawout construction and PXR20 LSIG ARMS trip unit. The device supports zone selective interlocking and is designed for reliable protection in heavy-duty motor feeders and main distributions, meeting stringent industry standards.
Ideal for industrial facilities, manufacturing lines, and data centers where high fault current protection, selective coordination, and reliable motor protection are essential. The Magnum PXR with LSIG ARMS is well-suited for main and feeder protection in large switchgear, where uptime, safety, and accurate fault isolation drive operating efficiency.
This breaker is UL Listed, CE Marked, and CSA Certified, with additional approvals referenced for global applicability. Compliance support helps streamline procurement and installation in regulated environments, while the UL and CSA certifications assist with end-user safety documentation and maintenance planning.
The motorized racking and drawout design minimize replacement time and field downtime, while Power Xpert Protection Manager compatibility enables proactive monitoring, event analysis, and streamlined servicing. The combination reduces maintenance costs, improves mean time to repair (MTTR), and enhances protection coordination across large electrical networks.
