It features a robust construction with an overvoltage category of III and a pollution degree of 2, ensuring reliability in challenging conditions.

The device accommodates screw connections with a conductor cross-section ranging from 0.2mm² to 2.5mm² for both flexible and rigid conductors.

It can handle maximum discharge currents of 10 kA in both line-line and line-earth configurations, ensuring outstanding protection against transient voltage spikes.

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 spikes are usually caused by lightning strikes and can reach up to 6000V, with current surges of over 3000A. The maximum size of the let-through voltage and current inrush 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.
