FAQs
The SPD100240D3L is designed for external mounting to electrical distribution equipment, featuring external side mounting and a NEMA 1 flush enclosure. It supports 240V delta (3W+G) configurations and provides a 100 kAIC interrupt rating, making it ideal for sidemounted protection in control panels and switchgear. Installation aligns with the SPD series guidance for retrofit projects and new builds.
It clamps transient voltages up to 100 kAIC, diverting surge energy away from protected equipment. This minimizes voltage spikes, reduces the risk of device failure, shortens downtime after surges, and extends component life. The built-in surge counter enables you to track events for maintenance planning and reliability analytics.
Yes. It is specifically rated for 240V delta (3W+G) systems with 320 L-G and 320 L-L operating voltages. The external side mounting and NEMA 1 enclosure are designed for indoor dry environments, making it well-suited for sidemounted protection in industrial control panels and distribution equipment.
The device carries UL 1449 certification, validating compliance with surge protection safety standards. It uses a robust NEMA 1 enclosure suitable for indoor installation and provides a 100 kAIC interrupt rating, aligning with common regulatory requirements for commercial and light-industrial protection.
With a 15-year warranty and an integrated surge counter, the SPD100240D3L lowers unexpected repair costs and downtime. External side mounting simplifies retrofit work, reducing labor hours.
