N8UE1+2/12.5 Type 1+2 AC Surge Protection Device

Name: N8UE1+2/12.5 Type 1+2 AC Surge Protection Device | Wanze
Brand: Wanze

Description

Designed for high-energy surge environments, the N8UE1+212.5 is a robust Type 1+2 SPD that handles both direct lightning strikes and switching transients. It offers an impressive impulse discharge current of 12.5kA (10/350μs) and a maximum discharge current of 50kA (8/20μs), ensuring superior protection for critical equipment. With a nominal discharge current of 15kA, a voltage protection level of 1.8kV, and a response time ≤100ns, it delivers reliable performance across a wide temperature range (–40℃ to +85℃) and altitudes up to 5000m. Available in 1P–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 flexible terminal compatibility (1.5–35mm² cables) make installation secure and versatile. IP20 rated for indoor use.
