Surge current
80 kA per phase
80 kA per phase surge rating provides robust protection against high-energy transients, reducing the risk of damage to drives, PLCs, and sensors and supporting longer equipment life in harsh plant environments. This capability translates to fewer unplanned outages and lower maintenance costs in manufacturing lines and process control rooms. The 277/480 V Wye (4W+G) input configuration ensures seamless integration with common industrial power distribution, simplifying retrofits and new installations alike. A NEMA 1 enclosure with internal disconnect delivers safe, code-compliant indoor mounting in control panels, minimizing service time during commissioning or replacement. UL 1449 listing confirms safety performance to industry standards, while compatibility with Power Xpert SPD expands monitoring and coordination capabilities for smarter protection. Compact dimensions and a manageable 6.8 lb weight support straightforward panel integration and retrofit projects without compromising protection.
