The four-pole configuration with the PXR25 LSIGAM trip unit enables precise protection and selective coordination, reducing the risk of unnecessary trips and improving machine uptime in motor-driven systems. This translates to lower maintenance costs and safer startup sequences in manufacturing lines and process facilities. The breaker’s high interrupting capacity of 100 kA and the frame rating of 4000 A (NNABCABC) provide robust fault protection for large power buses, enabling reliable operation in data centers, warehouses, and heavy industry while supporting future load growth. Compliance with UL Listed, ANSI, CE Marked, and NEMA standards simplifies procurement and installation in regulated environments, minimizing validation time and supporting cross-border projects. The substantial physical footprint—44.1 in wide, 16.8 in high, 16.3 in deep—and a 319 lb weight reflect the rugged construction designed for harsh plant conditions, with fixed horizontal mounting ensuring stable integration in switchgear. Power Xpert Protection Manager compatibility and the PXr trip-unit ecosystem enable advanced monitoring, event logging, and coordinated protection strategies, delivering lower total cost of ownership and improved safety benchmarks. Documentation and application notes, including zone selective interlocking guidance, support faster commissioning and risk reduction during field starts and upgrades.
