type 2 surge arrester / DIN rail
PSTxxxPV Type II



  • Type:

    type 2

  • Other characteristics:

    DIN rail


Surge protection devices Class II are developed to meet overvoltage
protection needs for PV photovoltaic networks against atmosphere
lightning. These units must be installed in parallel on the DC networks to be
protected and provide common and differential modes protection.
The electrical diagram is based on high energy MOVs equipped with
specific thermal disconnectors and related failure indicators.
