APS – 4P Low Voltage SPD CLASS 2 230VAC


  • IEC 61643-11 compliant, applicable to TT and TN systems. 
  • Four-pole pluggable design that is easily replaceable with any tools. 
  • This device has a high discharge capacity thanks to its 8/20 us waveform and Imax of 60kA. 
  • Options for both visual status indication and remote signal contact. 


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.
