Surge current
160kA per phase
The SPD MAX series offers 160kA per phase surge rating, delivering robust protection against large transients on each phase of a 480V delta system. This high rating helps safeguard motors, drives, and sensitive electronics from spikes that could cause insulation damage or unplanned downtime. It is a visible, measurable specification that supports reliability and compliance in demanding environments. The 480V delta (3W+G) configuration protects three-phase equipment with a solid grounding reference, enabling safer distribution and easier fault isolation. The NEMA 4 enclosure with an internal terminal block simplifies installation, guards wiring against dust and moisture, and reduces field wiring errors. UL 1449 certification ensures industry-standard protection performance, while compatibility with Eaton's Power Xpert SPD family enables coordinated protection across panels. Weight, dimensions, and rugged construction facilitate mounting in tight electrical spaces, easing field deployment and future scalability.
