Four-pole design with fixed vertical mounting provides robust, space-efficient protection in crowded panels. This configuration improves bus stability and reduces installation time, making retrofits predictable for OEMs and panel builders. With a 100 kA interrupting capacity, it safely clears high fault currents, minimizing arc energy and protecting downstream equipment. The result is shorter downtime and longer life for motor starters, drives, and feeders in manufacturing and process industries. The PXR20 LSI trip unit delivers precise protection and easy coordination with downstream devices. When used with Power Xpert Protection Manager, you gain real-time monitoring, event logging, and remote diagnostics that simplify maintenance planning. UL Listed, ANSI certification, and CE marking, along with CSA and KEMA validations, provide broad compliance coverage and procurement confidence. The Magnum frame also supports Power Xpert Release trip units and compatible accessories for scalable protection schemes. In practice, engineers report improved selectivity and faster fault isolation, reducing wasted energy and enabling safer machine downtime. This combination aligns with industry standards and maintenance budgets across automotive, packaging, and process sectors.
