FAQs
For correct installation, mount the MPSC083HEAXX2F as a three-pole unit in a standard Magnum frame enclosure with fixed horizontal mounting. Ensure proper clearance for the 16.2 in width and 16.8 in height, and align with existing bus connections and field wiring to minimize commissioning time and verify trip unit settings match system protection requirements.
The PXR20 LSIG ARMS trip unit provides selective, fast fault interruption with coordinated tripping across feeders. This reduces the risk of unnecessary outages on non-faulted circuits, supports motor protection schemes, and enables scalable protection strategies within Magnum panels, which is crucial for complex manufacturing lines and multi-feed distribution layouts.
Yes. The device is CE marked and UL Listed, with additional certifications including CSA and other recognized approvals, plus regional marks (ANSI, Lloyd's Register, KEMA, ABS, DNV GL). This broad certification portfolio supports multi-region procurement, installation, and regulatory compliance in diverse industrial environments.
Best suited for main feeders and distribution panels in manufacturing plants, processing lines, and large motor-driven systems. Its 800 A Iu rating and 100 kAIC interrupt capacity handle high fault currents, while the standard frame and three-pole configuration simplify integration with existing Magnum assemblies and Power Xpert protection workflows.
Expected ROI comes from reduced downtime due to improved protection coordination, lower maintenance costs through standardized parts and diagnostics, and faster regulatory approvals thanks to broad certifications. The PXR trip unit and Power Xpert Manager compatibility enable proactive maintenance and data-driven optimization of protection schemes.
