Four-pole Magnum PXR frame delivers robust protection for high-current distribution, supporting 800 A Iu and 100 kAIC. This combination enables precise protection coordination and reduces arc-flash exposure when used with selective coordination schemes. It is ideal for motor-control centers and large switchgear installations in manufacturing and data centers. Drawout vertical mounting with motorized racking makes replacement and testing faster and safer. Operators can rack breakers without opening enclosures, reducing outage times and improving reset reliability. Power Xpert Release trip unit PXR25 LSIGAM ARMS provides adjustable protection thresholds and enhanced arc sensing, improving selective coordination with downstream protections and minimizing nuisance trips. This supports safer, code-compliant operations across critical motor and process loads. The unit carries UL Listed, CE Marked, and NEMA compliant certifications, with CSA and KEMA certifications supporting global procurement and regulatory alignment. The standard frame with 14.6 in depth, 16.8 in height, and 21.2 in width, plus 160 lb weight, ensures compatibility with existing busways and mounting rails and accommodates heavy-duty applications.

FAQs

Yes, installation in standard MCCs is supported by the drawout vertical design with motorized racking. Ensure the enclosure is a standard four-pole frame and allows 21.2 in width, 16.8 in height, and 14.6 in depth. Confirm 800 A Iu and 100 kAIC short-circuit ratings align with the system, and that bus bars are compatible with Magnum PXR units.
The PXR25 LSIGAM is an advanced protection and coordination trip unit that integrates arc sensing and protection logic with LSIGAM ARMS. It offers adjustable pickup and protection curves, enabling selective coordination with downstream devices and minimizing nuisance trips. This translates to safer operation of motors and process loads and easier compliance with protection schemes in critical facilities.
Yes. The MPSC084MEAXX2S is UL Listed and CE Marked, with additional certifications including CSA and KEMA among others. This certification mix supports global procurement and regulatory alignment for international projects. For multi-site deployments, verify any site-specific requirements such as ABS or DNV GL where applicable.
Ideal for motor-control centers, large switchgear, data centers, and manufacturing lines requiring high interrupt ratings and reliable protection. The four-pole Magnum frame handles heavy loads, while drawout mounting supports hot-swappable maintenance. Use with Power Xpert Protection Manager workflows for scalable automation in energy-intensive operations, with straightforward integration into existing cabinets and protective relays.
Maintenance benefits include reduced downtime due to motorized racking and safer, faster maintenance cycles. The 800 A Iu and 100 kAIC provide long-term fault protection, while standard dimensions and frame compatibility minimize installation risk and site adaptation costs. UL/CE certifications streamline multi-site deployments, lowering total cost of ownership and accelerating project delivery.
