Power Xpert Release (PXR) 25 trip unit delivers precise, staged protection with advanced coordination. This improves fault isolation and minimizes unintended outages across complex motor and feeder networks. Designed for Magnum breakers in industrial power systems, it supports scalable protection in motor control centers and distribution panels. Drawout vertical mounting with extensions simplifies retrofit and field maintenance. Installation time is reduced and maintenance crews can access trip units without panel removal, improving uptime and safety. Best fit for retrofits in legacy panels where space and alignment are critical. High interrupting capacity of 85 kA and 6000 AIC ensures protection for large loads and short-circuit events. Coupled with a 3-pole design, this configuration improves coordination across phases and reduces arc energy exposure. Applications include heavy motor loads and critical process lines in manufacturing plants. Compatibility with Magnum PX R trip units and Protection Manager allows centralized protection management. Operators gain real-time diagnostics, event records, and remote configuration to streamline engineering workflows. Certified to UL, KEMA, and Lloyd's Register standards provides regulatory confidence. Compact dimensions and a drawout design simplify panel integration and spare-part availability for ongoing maintenance.
