The four-pole design with a 4000 A interrupt rating and 100 kA short-circuit rating delivers robust feeder protection and enables selective coordination, reducing downstream damage in large motor circuits and critical feeders. This translates to fewer nuisance trips and shorter repair times in MCCs and process lines. The PXR20 LSIAM trip unit provides advanced protection logic for fast, accurate tripping and easier fault diagnostics, improving overall system reliability and maintenance planning. Drawout vertical mounting simplifies installation and replacement, minimizing outage duration during panel upgrades or retrofits in existing switchgear. Double-frame Magnum compatibility reduces spare parts variety and procurement effort for multi-bay installations across manufacturing plants. Integration with Power Xpert Protection Manager enables remote monitoring, event logging, and coordinated protection strategies that support predictive maintenance and asset optimization. All-round certifications and global compliance support cross-border deployments with confidence.
