FAQs
SPD100240S4K is designed for 120/240V split-phase systems and ships in a NEMA 1 indoor enclosure. Its 100 kA per phase surge rating protects breakers, controllers, and drives in standard industrial panels, reducing nuisance trips and extending equipment life. This compatibility minimizes wiring complexity and simplifies panel board upgrades or retrofits.
The device provides robust transient suppression (100 kA per phase) and UL 1449 listed protection, safeguarding critical components from voltage spikes that cause faults and downtime. In manufacturing lines, this translates to fewer unscheduled outages, lower maintenance costs, and longer service intervals for sensitive equipment such as PLCs and servo drives.
Yes. Its 3.48 in depth, 7.47 in width, and 12.05 in height fit common cabinet footprints, and it integrates seamlessly with Eaton’s Power Xpert SPD family. For retrofits, the unit’s UL 1449 compliance and standard 120/240V split-phase rating simplify procurement and commissioning, while minimizing changes to existing wiring and protection schemes.
SPD100240S4K carries UL 1449 certification, confirming compliance with industry-standard surge protection safety requirements. It is designed for indoor use in a NEMA 1 enclosure, ensuring suitable environmental protection for control rooms and panel boards. This combination supports regulated procurement and reliable long-term operation.
By limiting transient damage to critical devices and reducing downtime, the SPD helps extend the life of power electronics and minimize costly replacements. The device’s compatibility with Eaton’s protection ecosystem also streamlines maintenance training and service planning, delivering faster fault resolution and lower total cost of ownership over the system lifecycle.
