L.V Surge Protection Device

Sigma Elektrik Surge Protection devices designed in class I (type 1, B type)- class II (type 2, C type)– class I+II (type 1+type 2, B+C type) – class III (type 3, D type) in accordance with IEC /EN  61643-1 and CE standards with 1,2,3 and 4 poles. Surge protection device protects the power network and electrical equipment by discharge the surge coming from lightning events or from switching operations. The high transient voltage is limited to acceptable limits by surge protection device thus power network and electrical equipment are protected.
