FAQs

For best results, ensure vertical drawout mounting clearances meet the breaker’s 16.3 in depth and 44.1 in width footprint, with unobstructed motorized rack access. Verify alignment with the bus, confirm the PXR25 LSI ARMS unit is properly seated, and perform a factory-commissioning sequence outlined in the Magnum PXR guide to minimize start-up delays and ensure proper protection coordination.
The PXR25 LSI ARMS trip unit enables selective protection by coordinating misoperation protection with downstream devices. This reduces unnecessary trips during faults, improves reliability for critical loads, and supports fast fault isolation. In applications with multiple motors and feeders, this leads to lower downtime and enhanced system availability.
Yes. With a 6000 A Iu rating and 100 kAIC interrupt capability, the MPSC604MEAXX2Q is designed for heavy-duty motor protection in MCCs. The four-pole frame supports synchronous and induction motors, while the motorized racking and drawout design streamline maintenance and replacement without compromising safety.
The unit carries UL Listed, ANSI KEMA Certified, and CSA Certified marks, with additional regional confirmations such as CE and CCC marks in the broader product family. This combination supports rapid regulatory approvals for North American and international deployments, reducing project risk.
Plan proactive upkeep with routine inspection of the drawout mechanism, trip unit calibration checks, and inspection of enclosure sealing for dust ingress. Leverage Power Xpert Protection Manager for monitoring trip unit health, and reference the renewal parts and accessories documentation to secure compatible components and minimize downtime during service intervals.
