Product Description

Surge Arresters

SLP-075 VB

SLP-130 VB

SLP-275 VB

SPD type 2 – surge arrester Replaceable module, visual fault signaling

Efficient varistor connected in series with an encapsulated spark gap. To be installed in low-voltage distributions at the boundary of LPZ 1 and LPZ 2 zones. Designed to protect distributions and equipment against the overvoltage effects induced during a lightning strike and to prevent switching overvoltage in areas with higher storm activity or to protect measuring circuits as a 1st protection level. In idle state it has

very little leakage current, which remains stable for the duration of the service life; protective elements are not subject to ageing.
