Four-pole design with fixed vertical mounting and a Magnum frame delivers robust protection for distribution panels. This configuration improves selective coordination and short-circuit response, reducing arc energy and equipment damage in industrial environments. It is ideal for motor control centers and machine panels where reliability and space utilization matter. The Power Xpert Release (PXR) 20/25 trip unit compatibility provides advanced protection features, enabling precise coordination with upstream devices and easier field configuration, which translates to fewer nuisance trips and faster commissioning in complex lines. The unit offers 85 kA interrupting capability and 5000 A nominal withstand (NABCNABC), supporting fault-current conditions in large panels and minimizing system downtime. Global compliance—UL Listed, CE Marked, and NEMA compliant—streamlines procurement and regulatory approvals for international projects. Renewal parts, installation guides, and application notes from Eaton further reduce maintenance lead times and extend lifecycle. Together, these attributes support a measurable reduction in total cost of ownership and improved panel uptime.
