Weidmuller VPU III R 12V/4KV AC/DC 1351550000 Surge Voltage Arrester

Zinthu zoteteza kugwedezeka kwa Weidmüller VPU I (Mtundu I), VPU II (Mtundu II) ndi VPU III (Mtundu III) zimachepetsa bwino kusakanikirana komwe kungachitike chifukwa cha ma voltage othamanga pang'onopang'ono, ngakhale pang'ono kwambiri poyerekeza ndi malire omwe amaperekedwa ndi kusakanikirana kwa insulation malinga ndi EN 60664-3 / DIN VDE 0110-3. Izi zikutanthauza kuti kukhazikitsa konseko kumakhala ndi zovuta zochepa. Zomangira zimagwirizanitsidwa pogwiritsa ntchito njira zaukadaulo. Izi zikutanthauza kuti kugawa pakati pa Mitundu I, II ndi III sikofunikira. Zomangira zimayesedwa malinga ndi muyezo wazinthu IEC 61643-11 / DIN EN 61643-11 ndipo zitha kuyikidwa m'makina malinga ndi IEC 61643-12 / VDE 0675-6-12 ndi IEC 62305-4 / VDE 0185-4. Chipangizo choteteza mphezi ndi kugwedezeka ichi ndi choyenera kuyikidwa m'makina opangira magetsi. Weidmüller amapereka zinthu zosiyanasiyana kutengera mtundu wa netiweki ya mains ndi mulingo wa voltage. Chipangizo chapadera choteteza cha Mtundu I ndi Mtundu II chikupezekanso kuti chigwiritsidwe ntchito pa photovoltaic.
