Surge current
100 kA per phase
The SPD100220Y4A delivers 100 kA per phase surge current, providing a high-energy path to shunt transient spikes away from protected circuits. This capability minimizes nuisance trips and protects sensitive drives, timers, and controllers, reducing unplanned downtime and maintenance costs. It is well suited for manufacturing lines and process controls where transient events pose a frequent risk. With a 127/220 V Wye (4W+G) configuration, the unit readily accommodates common industrial feeders and grounding schemes, simplifying wiring and improving protection reliability across line and neutral connections. Direct bus mounted compatibility with PRL1a, 2a, 3a, 3e panels enables tight integration with the Power Xpert SPD ecosystem, reducing enclosure footprint and speeding up commissioning. The compact footprint—3.48 in depth, 12.05 in height, 7.47 in width—plus a 6.8 lb weight make field installation straightforward and serviceable. UL 1449 certification ensures the device meets recognized safety and performance standards for surge protection, supporting compliant installations in regulated facilities. Power Xpert SPD compatibility provides an upgrade path for enhanced monitoring and protection capabilities as your protection strategy evolves.
