SPD, also known as a power surge, is, as the name implies, a momentary overvoltage in excess of normal operating voltage. Essentially, a surge is a violent pulse that occurs within a few millionths of a second and can be caused by heavy equipment, short circuits, power switches or large engines. Products containing surge isolators can effectively absorb huge bursts of energy to protect connected equipment from damage.

Surge protectors are suitable for use in power supply systems with AC 50/60 Hz and a rated voltage of 220V/380V to protect against indirect and direct lightning effects or other transient overvoltage surges for surge protection requirements in domestic dwellings, the tertiary sector and industry.
