The four-pole construction with fixed horizontal mounting provides robust protection in demanding switchgear. It enables denser panel layouts and faster, more predictable installation for motor feeders. High interrupting capability of 100 kA with a 4000 A frame rating confines fault energy and protects feeders downstream. This reduces component damage and unexpected outages in heavy industry. The PXR20 LSI trip unit delivers precise protection coordination with Magnum protection platform, translating to fewer nuisance trips and improved selective coordination across multi-panel installations. Global compliance is supported by CE marking, UL Listed status, NEMA compatibility, and KEMA and CSA certifications, facilitating international projects and regulatory acceptance. Physical footprint details—16.3 in length, 16.8 in height, 44.1 in width, and 319 lb weight—aid layout planning and stable mounting in large enclosures. Compatibility with Power Xpert Protection Manager and renewal parts simplify maintenance planning, enabling firmware and trip-unit updates to extend service life for retrofit and new-building projects.
