FAQs

The MPS8503HEAXX2H is designed for seamless integration within Magnum PXR installations and is compatible with Power Xpert Release trip units. This facilitates coordinated protection across existing panelboards, enabling straightforward retrofits and scalable protection schemes without major enclosure or wiring changes.
The PXR20 LSIAM trip unit offers adjustable protection curves, enhanced coordination, and rapid fault isolation. It supports precise overcurrent protection for three-pole configurations, helping prevent nuisance trips while protecting downstream equipment in motor circuits and critical feeders.
This model carries UL Listed, KEMA Certified, ANSI, CSA Certified, Lloyd’s Register Certified, CE Marked, and other approvals. These certifications support compliance across North America, Europe, and key international markets, reducing procurement risk and facilitating multi-region project execution.
Yes. With its high interrupting capacity of 5000 A (ABCABC) and the PXR20 LSIAM trip unit, the breaker supports selective coordination in complex power distribution. Typical applications include main feeders and large motor circuits where precise tripping coordination minimizes outages and preserves critical loads.
Plan for fixed horizontal mounting in compatible enclosures, accounting for its 16.3 in depth, 16.8 in height, and 31.1 in width. Use the available manuals and zone selective interlocking resources to streamline commissioning, reduce field wiring time, and lower lifecycle costs through reliable protection and minimal unscheduled downtime.
