Product Details

DEHNventil Surge Arresters Type 1/2

Type 1 and 2 prewired spark gap based combined lightning current and surge arresters consisting of a base and plug in modules.

Maximum system availability and reliability due to the RADAX Flow follow current limitation
No tripping of 20amp gL/gG fuses up to short circuit currents of 50kA
Discharge capacity of 100kA with 10/350 microsecond lightning waveform
Capable of protecting terminal equipment
Operating state and fault indication with indicator flag and/or optional remote contact in base
Easy replacement of protection modules requires no tools due to lock in system.
Coordinated with other Dehn Redline products to meet BS7671 amendment 1

Surge Protection Devices, SPDs (DIN-rail)

Voltage surges, often referred to as spikes or transients are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning and can reach up to 6000V, with current surges of over 3000A. The maximum size of the voltage and current surges depends on the location within the building's wiring system. BS7671: 2011 Amendment 1 Sections 443 and 534 cover risk assessment and provides guidance on protection of electronic equipment for installation engineers to follow. The fullest information on lightning and surge protection comes from the BSEN 62305 series of standards.
