FAQs
SPD100240D1N uses external side mounting, which simplifies integration with existing electrical distribution equipment. This design reduces installation time, minimizes panel space requirements, and allows for easier retrofits in control cabinets or standalone distribution enclosures while maintaining access for service and testing.
The SPD100240D1N provides a 100 kAIC interrupt rating with a 240V delta (3W+G) configuration and an operating voltage of 320 V line-to-ground and 320 V line-to-line. These specs support robust protection against transient surges in typical industrial three-phase networks.
Yes. The device comes in a NEMA 4X enclosure, which offers weather-resistant and washdown-capable protection. This makes it suitable for outdoor installations, damp plant floors, and environments where exposure to moisture and dust is a concern.
SPD100240D1N is UL 1449 listed, ensuring compliance with recognized surge protection standards. The rugged enclosure rating (NEMA 4X) further supports reliability in challenging environments, contributing to safer and more compliant electrical protection installations.
By reducing transient-induced equipment damage and downtime, SPD100240D1N extends the life of downstream devices and minimizes unexpected maintenance. Its compatibility with the SPD series and sidemount design also lowers installation and retrofit costs across multiple sites, delivering a favorable total cost of ownership.
