Function

The surge protective device (SPD) protects electrical systems and sensitive equipment from transient overvoltages caused by lightning strikes or switching events. It safely diverts surge energy to earth, limiting the voltage reaching downstream devices. The Type 1+2 design allows it to handle direct lightning impulses while also providing protection against switching transients.
