High interrupt rating and Iu capability translate to robust fault handling, reducing damage downstream and improving overall system reliability; the business impact is measurable uptime and safer protection for critical lines in manufacturing, data centers, and process plants. The four-pole configuration and drawout vertical mounting enable full-phase protection with simple hot-swapping during maintenance, cutting downtime and enabling faster panel upgrades in existing installations. The PXR20 LSI ARMS trip unit delivers selective protection and arc-flash energy management, improving compliance and reducing nuisance trips in complex protection schemes. Compatibility with Magnum PXR frames and double-standard construction simplifies retrofits and new builds alike, lowering engineering time and training costs. The unit carries UL, CE, and CSA certifications, aligning with global procurement standards and reducing supplier risk while meeting local regulatory requirements. With dimensions of 16.3 in depth, 16.8 in height, and 44.1 in width, plus a 319 lb weight, installation foot-prints and handling are well-defined for panel design and crane-lift planning. This combination supports long-term lifecycle cost reduction and predictable maintenance budgets.
