What is Surge Protection?

Recently introduced standards put equal importance on protecting the electrical installation and electrical equipment as to the building itself.

Surge protective devices (SPD) assist in the protection of valuable electrical and electronic equipment against transients, originating from lightning and also from switching sources. These transients can cause damage ranging from the premature ageing of equipment, logic failures and down time, to the complete destruction of equipment within the entire electrical installation. Products such as LCD screens, data servers and industrial equipment such PLC’s are critical to business activity.

The consequential losses suffered during such events i.e. downtime and lost production, can be very high.

We offer a wealth of experience in helping to decide which product best suits your needs.
