Fixed-horizontal mounting and a three-pole design simplify installation and bus-bar alignment, reducing wiring time and labor costs on day-one. The 2000 A current rating with a 100 kA short-circuit withstand rating delivers robust protection for high-demand feeders, helping to minimize nuisance trips and equipment damage during faults. Because this model ships without a trip unit, it offers installation flexibility: select a Power Xpert Release PXR trip unit later to achieve precise coordination with upstream protections and system requirements, lowering long-term retrofit risk. UL Listed, CE Marked, and multiple international certifications support global compliance, accelerating project approvals and reducing risk in multi-site deployments. The unit’s standard frame and fixed horizontal mounting ensure straightforward integration with Magnum PXR devices and common enclosures, improving upgradeability and stock efficiency for maintenance teams. Industry best-practice documentation is readily available to inform deployment strategies, such as zone selective interlocking and selective-coordination studies.
