Features:
Type 2 AC surge arrester for surge protection of low-voltage power supply systems at lightning protection zones 1-2 and higher boundary lines. The lightning current waveform on the SPD SLP40 series AC Type 2 surge protection device is 8/20 s.
The SPD SLP40 series of AC Type 2 surge protection devices are intended to protect against transient overvoltages at the service entrance of low-voltage systems or near sensitive equipment.
