FAQs

The MPSC4A4HEAXX2H uses a fixed horizontal mounting suitable for standard four-pole assemblies and is designed to integrate with Power Xpert Protection Manager workflows. Its 100 kA interrupting rating supports high-current feeders, and the PXR20 trip unit provides zone-selective interlocking to align with existing protection schemes. Verify mounting footprint and bus configuration in your panel design before installation.
The PXR20 LSIAM trip unit delivers fast, selective tripping with zone-selective interlocking, reducing nuisance trips and limiting fault impact to only the affected section. This improves equipment uptime and simplifies coordination across downstream devices, which is particularly beneficial in facilities with complex motor loads and shared feeders.
Yes. The MPSC4A4HEAXX2H carries UL Listed, CE Marked, and CSA Certified approvals, along with KEMA, ANSI, Lloyd's Register, ABS, and DNV GL certifications. This broad certification suite supports global deployment in regional panels, reducing compliance risk for multinational projects.
Key dimensions include a 16.3 in depth, 16.8 in height, and 44.1 in width, with a weight of approximately 319 lb. It’s a fixed horizontal-mount, four-pole device designed for high-current environments. Ensure cabinet clearance, bus-bar alignment, and proper torque on mounting hardware to achieve reliable operation and maintain coordination with adjacent devices.
Upgrading to this model provides ROI through reduced downtime from improved selective protection and faster fault isolation, lower maintenance costs due to robust construction and long service life, and better conformity with international standards for global projects. The combination of 100 kA interrupting capability and PXR20 protection supports reliable, scalable protection across expanding motor and process loads.
