Surge current
100 kA per phase
100 kA per phase surge rating translates to higher transient energy absorption, reducing component damage and extending the life of drives, PLCs, and contactors. This reduces downtime, minimizes field service calls, and lowers spare-parts burdens for maintenance teams. Ideal for automation panels in manufacturing lines and critical power feeds, the SPD100400Y4M helps sustain production throughput even during severe utility or switching events. The 230/400 V Wye (4W+G) voltage rating enables plug-and-play integration with common industrial power systems, simplifying spec alignment and reducing installation rework while improving protective coordination between upstream breakers and downstream devices. Applications include panelboards, motor control centers, and distribution boards across plant floors. UL 1449 listing demonstrates safety and performance compliance, while the NEMA 1 enclosure with internal disconnect offers rugged protection and safe servicing on busy lines. Power Xpert SPD compatibility ensures seamless integration with Eaton's protection ecosystem, enabling centralized monitoring and coordinated surge management. The unit’s compact footprint and straightforward installation reduce commissioning time and enclosure footprint, supporting retrofit projects and flexible layouts in manufacturing environments.
