Surge current
100 kA per phase
The 100 kA per phase surge capability is the core feature, delivering high-energy clamping to protect downstream gear, which translates to measurable improvements in equipment reliability and reduced unplanned downtime. In practice, this means fewer night-shift service calls and lower root-cause analysis costs after transient events, especially in manufacturing lines and critical infrastructure. The unit’s 230 V rating aligns with common plant distribution, while its compact footprint and NEMA 4 enclosure with internal disconnect simplify field mounting and serviceability, reducing installation time and panel real estate requirements. Compatibility with Power Xpert SPD solutions enables seamless integration into existing protection schemes, enabling centralized monitoring and faster fault isolation. Moreover, UL 1449 certification and rugged enclosure design reassure procurement teams that the solution meets industry standards and harsh operating conditions.
