Distribution-class surge arrester 3EK1, metal-oxide (MOV), 3EK distribution series — detailed ratings on request

• Official product family under Switching Products → Surge Arresters → Distribution Surge Arresters (3EK) in the GT product hierarchy, alongside 3EK3, 3EK4, 3EK7 and 3EK8
• Based on the gapless metal-oxide varistor (MOV) — the core of every Siemens Energy arrester: low resistance during surges, high resistance in normal operation, stable characteristics over lifetime
• The 3EK distribution-class family protects transformers, circuit breakers, MV switchgear/panels and distribution lines in medium-voltage networks
• From a manufacturer that has designed and built medium- and high-voltage surge arresters since 1925, with type tests performed in independent PEHLA-certified laboratories and a routine test certificate shipped with every arrester
• Family-specific electrical and mechanical data for 3EK1 is not part of the current published MV catalog (which details the 3EK7/3EK8 lines) — detailed ratings, dimensions and ordering data are available on request
