It employs advanced technology to absorb and redirect transient voltage surges, ensuring that connected equipment remains unharmed during lightning strikes or electrical switching events.

The inclusion of robust components and compliance with IEC 61643-11 standards ensures durability and dependable performance. The design is specifically focused on preventing equipment damage due to high voltage transients.

It provides maximum continuous operating voltage up to 280V, with the capability to withstand temporary overvoltages, making it suitable for a wide range of applications in both residential and industrial environments.

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.
