Eaton SPD100240H3K Surge Protection Device - UL 1449
Part Number: SPD100240H3K
Quick Summary
The Eaton SPD100240H3K surge protection device protects electrical panels from transient overvoltage in industrial and commercial environments. This solution addresses the frequent challenge of nuisance surges that shorten equipment life and trigger unexpected downtime. It is UL 1449 listed and housed in a rugged NEMA 1 enclosure with external side mounting, rated for 240V delta (4W+G) systems and 100 kAIC events. By absorbing spikes before they reach sensitive loads, it helps extend service life, reduce maintenance costs, and improve uptime. For panel builders and integrators, the SPD offers reliable protection with a 15-year warranty and an integrated surge counter, supporting compliance and long-term total-cost-of-ownership improvements.
