N8UE1+2/8 Type 1+2 AC Surge Protection Device

Description

Built for demanding environments, the N8UE1+28 is a versatile Type 1+2 surge protection device, available in standard and NPE versions. It operates reliably from –40℃ to +85℃and at altitudes up to 5000m. The standard model (N8UE1+2/8) delivers a 7kA impulse discharge current (10/350μs) and a 1.5kV voltage protection level, while the NPE variant (N8UE1+2/8–NPE) offers a higher 25kA impulse current and 1.8kV Up for enhanced protection between N–PE. Both share a 50kA maximum discharge current (8/20μs), 20kA nominal discharge current, and ultra-fast response time (≤25ns for standard, ≤100ns for NPE). Available in 1P–4P configurations, they mount easily on a 35mm DIN rail, support up to 125A backup fuses, and feature flame-retardant UL 94 V-0 housing. IP20 rated for indoor use.
