FAQs

For new panel installations, plan for four-pole protection with a drawout vertical mounting to simplify removal and inspection. Ensure panel bus clearance accommodates the 44.1 in width and confirm the site power system supports the 100 kA interrupting rating. Verify Power Xpert Release trip unit compatibility if digital protection management is required.
The PXR20 LSI trip unit provides precise, engineered protection with advanced protection logic, improving selectivity and reducing nuisance trips. In practice, this means more stable feeder coordination, faster fault isolation, and easier compliance with strict industrial protection standards while maintaining system uptime.
Yes. With a 100 kA interrupting rating and 6000 A withstand capability, it is designed to tolerate high fault currents typical of heavy industry, data centers, and large facility feeders. This makes it a robust choice for future-proofing critical power distribution.
The unit carries UL Listed, CSA Certified, and CE Marked certifications, along with NEMA compliance. These credentials simplify procurement across global sites, support regulatory adherence, and reduce risk when sourcing components for multinational installations.
The combination of precise protection, fast maintenance via drawout mounting, and centralized protection management with Power Xpert reduces unplanned downtime, speeds commissioning, and lowers lifecycle costs. In practice this translates to improved equipment availability and lower maintenance overhead over the life of the installation.
