FAQs

Before installation, verify the panel enclosure supports four-pole, drawout breakers and vertical mounting. Check bus bar alignment, mounting rails, and enclosure clearance to accommodate the 16.3 in depth, 16.8 in height, and 44.1 in width. Ensure PXR20 LSI trip unit wiring is accessible, and configure with Power Xpert Protection Manager for monitored protection settings.
The PXR20 LSI trip unit provides load-sensing protection with advanced logic, enabling selective coordination and faster fault clearance. This reduces arc energy exposure, minimizes downstream damage risk, and improves uptime on motor feeders and critical loads, especially in high-demand industrial environments.
Ideal for industrial power distribution, motor control centers, and process lines requiring reliable protection with fast fault isolation. Its high SCCR and drawout design suit high-current, high-demand installations with frequent maintenance or replacement needs, while supporting scalable protection schemes for evolving plants.
The unit carries UL Listed and CSA Certified marks, plus ANSI certification, Lloyd’s Register and other global approvals. It also features CE marking and NEMA compliance, enabling installation across North America, Europe, and select international markets with confidence.
Expect reduced downtime from faster maintenance enabled by the drawout design, improved protection reducing fault events, and lower lifecycle costs through compatibility with Eaton protection software. Zone selective interlocking resources and comprehensive manuals support long-term reliability and streamlined field service.
