The surge protector leverages Metal Oxide Varistor (MOV) technology, allowing it to handle transient voltages effectively. This technology is known for its fast response time, ensuring that equipment is shielded from electrical surges promptly.

It is designed for clip-on mounting to DIN rails, ensuring quick installation and alignment in standard electrical enclosures. This mounting style enhances the workflow during installation and maintenance tasks.

The device operates efficiently across a temperature range of -25 to +60 °C and can function at altitudes up to 2000m, making it suitable for diverse installation locations while maintaining performance reliability.

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.
