FAQs
External side mounting should be planned with access to the enclosure, clearance for terminal connections, and alignment with existing SPD series configurations. Route conductors to L-N, L-G, L-L, and N-G paths per the installation manual and maintain proper labeling for easy future servicing.
The device clamps transient surges up to an 80 kAIC interrupt rating, diverting excess energy away from protected circuits. It provides multiple surge paths (L-N, L-G, N-G, L-L) suitable for common 4W+G configurations, reducing the risk of equipment damage and downtime in industrial power distributions.
Yes. The unit uses a NEMA 4X enclosure designed for harsh or outdoor environments, enabling reliable operation in wet, dusty, or washdown areas while supporting external side mounting for flexible installation.
SPD080480Y1O is UL 1449 listed and housed in a NEMA 4X enclosure. This combination provides verified surge protection performance and robust environmental protection suitable for demanding industrial settings.
Investing in SPD080480Y1O can lower total cost of ownership through reduced downtime and equipment damage. The 15 year warranty and UL 1449 certification, combined with a straightforward external-mount installation, support predictable maintenance planning and longer asset life without frequent replacements.
