N8UE2+3-30 Type 2+3 AC Surge Protection Device

Description

The N8UE2+3-30 is a compact Type 2+3 surge protection device, ideal for protecting sensitive electronic equipment against transient overvoltages caused by switching events and indirect lightning strikes. It features a maximum discharge current of 30kA (8/20μs) , a nominal discharge current of 15kA, and a composite wave open-circuit voltage of 20kV (1.2/50μs) , delivering reliable suppression with a low voltage protection level of 1.5kV. With an ultra-fast response time ≤25ns, it ensures critical loads stay protected. Available in 1P–4P configurations, it mounts on a standard 35mm DIN rail and supports backup fuses up to 125A. The flame-retardant UL 94 V-0 housing and versatile terminals (1.5–35mm² cables) make installation easy and secure. Operates flawlessly from –40℃ to +85℃ and at altitudes up to 5000m. IP20 rated for indoor use.
