N8UE1+2/6 Type 1+2 AC Surge Protection Device

Designed for harsh environments, the N8UE1+26 offers reliable surge protection across a wide operating range (–40℃ to +85℃) and altitudes up to 5000m. With a combined Type 1+2 classification, it handles both direct and indirect lightning strikes, featuring a 6kA impulse discharge current (10/350μs) and 50kA maximum discharge current (8/20μs). The ultra-fast response time (≤25ns) and low voltage protection level (1.5kV) ensure sensitive equipment stays safe. Available in 1P–4P configurations, it mounts easily on a 35mm DIN rail and supports up to 125A backup fusing. Flame-retardant housing (UL 94 V-0) and screw terminals for 1.5–35mm² cables make installation secure and versatile. IP20 rated for indoor use.
