N8UF2-30 Type 2 AC Surge Protection Device

Name: N8UF2-30 Type 2 AC Surge Protection Device | Wanze
Brand: Wanze

Description

The N8UF2-30 is a robust Type 2 surge protection device, available in standard and NPE versions, engineered to protect electrical systems and sensitive equipment from transient overvoltages caused by switching events and indirect lightning strikes. The standard model delivers a maximum discharge current of 30kA (8/20μs) , a nominal discharge current of 15kA, a low voltage protection level of 1.5kV, and an ultra-fast response time ≤25ns. The NPE variant adds a 12.5kA impulse discharge current (10/350μs) for enhanced protection between N–PE, with a response time ≤100ns. Available in 2P and 4P configurations, it mounts easily on a 35mm DIN rail and supports backup fuses up to 125A. The flame-retardant UL 94 V-0 housing and wide terminal compatibility (1.5–35mm² cables) ensure secure and flexible installation. Operates reliably from –40℃ to +85℃ and at altitudes up to 5000m. IP20 rated for indoor use.
