Surge Protection Devices (SPD's)

Zetmet Limited now offer a selection of Schneider Surge Protection Devices (SPD’s) online at discounted prices. SPD’s are the latest development in the circuit protection sector. They are used to protect the electrical installation from transient overvoltages.

A good example of this is a lighting strike. These can cause an increase in voltage from 230V up to 6kV, resulting in damage to electronic components such as processors, screens and memory. However, a surge protection device is able to damp the spike down. This helps reduce or even prevent damage to your valuable possessions.
