FAQs
The SPC120480D1P is designed for 480V delta configurations and plugs into standard protection schemes within commercial and industrial panels. Its external side mounting simplifies retrofits, enabling quick integration with existing feed-thru and main distribution setups. This results in minimal downtime during upgrades while maintaining consistent surge protection across the panel.
UL 1449 listing verifies surge protection performance and safety under transient conditions, giving engineers a verifiable standard to meet regulatory and safety requirements. Combined with a 120 kAIC rating and a NEMA 4X enclosure, this device supports compliant installation in a variety of environments, from manufacturing floors to outdoor enclosures.
Yes. The SPC120480D1P uses a NEMA 4X enclosure, which provides protection against dust, water, and corrosion in demanding environments. This makes it appropriate for outdoor installations, wash-down areas, and other harsh settings common in food processing, pharmaceutical, and industrial facilities.
External side mounting allows straightforward mounting on the exterior of control panels, reducing internal space needs and simplifying cable routing. Plan for adequate clearance, consider potential exposure to environmental factors, and ensure compatibility with the SPC series mounting footprint to optimize accessibility for maintenance and testing.
Implementing the SPC120480D1P helps reduce unplanned downtime, extend equipment life, and lower maintenance costs by limiting transient damage to power electronics and controllers. With a 10-year warranty and UL 1449 compliance, facilities often see lower total cost of ownership as protection aligns with longer asset lifecycles and fewer replacement parts.
