High surge protection is the core capability of SPD100240S1P, delivering up to 100 kAIC interrupt rating to divert damaging transients away from sensitive loads. This directly reduces risk of semiconductor failure, downtime, and warranty claims. In practice, it protects critical drives, controls, and sensors across 120/240 V panels, improving system availability in manufacturing lines and data centers. Designed for 120/240 V split-phase power, the device offers reliable, compatibility-friendly protection for both line and neutral paths as well as ground paths. This alignment with common panel configurations minimizes rework during installation and accelerates commissioning, delivering faster time-to-protection for new builds and upgrades. With a NEMA 4X stainless steel enclosure and external side mounting, SPD100240S1P withstands harsh environments, including wash-down areas and outdoor installations, reducing enclosure-related failures and lifecycle costs. The operating voltage options (150 L-N, 150 L-G, 150 N-G, 300 L-L) provide comprehensive clamping across all critical conductors, delivering uniform protection across feeders and downstream loads. Coupled with UL 1449 certification and a 15-year warranty, it offers long-term confidence for procurement and maintenance teams. External sidemount installation supports straightforward retrofit to external distribution equipment, simplifying field upgrades and accelerating deployment for engineers and panel builders.

FAQs
SPD100240S1P is a surge protection device designed for 120/240 V split-phase systems. It is intended for installation external to electrical distribution equipment, using a sidemount configuration on a NEMA 4X stainless steel enclosure. This makes it suitable for outdoor, wash-down, or retrofit applications where space inside panels is limited and protection must be readily accessible for maintenance.
100 kAIC is the interrupt rating, indicating the maximum surge current the device can safely interrupt. For facility protection, this translates to strong defense against high-energy transients from lightning or utility events, reducing the likelihood of equipment damage, downtime, and related maintenance costs across protected loads like drives, PLCs, and sensors.
Yes. The unit uses a stainless steel NEMA 4X enclosure designed for exterior and wash-down environments. External side mounting simplifies retrofit and external wiring configurations, minimizing interior panel work and facilitating robust protection in challenging locations.
The device provides protection for L-N, L-G, N-G, and L-L connections with operating voltage ratings of 150 L-N, 150 L-G, 150 N-G, and 300 L-L. This offers comprehensive, multi-path surge protection for common 120/240 V distributions, supporting reliable operation of connected equipment across complex circuits.
SPD100240S1P carries UL 1449 certification for surge protection safety and includes a 15-year warranty. These factors support regulatory compliance, consistent performance over time, and lower total cost of ownership for procurement and maintenance teams.
