Surge current
100 kA per phase
The surge protection device delivers 100 kA per phase, enabling robust transient handling that minimizes unexpected downtime and equipment wear in critical processes. This performance translates to reduced maintenance costs and higher line availability for manufacturing lines, data centers, and critical utilities that rely on stable power. The 120/208 V wye (4W+G) rating supports common commercial feeders, ensuring broad applicability without custom transformers or rework. Direct bus mounted compatibility with PRL1a, 2a, 3a, 3e reduces wiring complexity, speeds installation, and lowers labor risk during retrofits or new builds. UL 1449 certification provides regulatory assurance, aiding passing inspections and supplier qualification. The Power Xpert SPD ecosystem streamlines serviceability, diagnostics, and coordinated protection across Eaton power management assets. Final sizing and mounting considerations fit compact spaces, aiding enclosure planning and maintenance efficiency.
