Drag:<\/strong><\/p>\n

Typ:\u00a0T1+T2 \u00d6versp\u00e4nningsskydd<\/p>\n

Svarstid: \u2264100ns<\/p>\n

M\u00e4rkta anslutningar.<\/p>\n

Komposittyp: 3P+N.<\/p>\n

Montering: standardskena 35mm.<\/p>\n

Designad f\u00f6r att skydda l\u00e5gsp\u00e4nningsinstallationer fr\u00e5n elektriska \u00f6versp\u00e4nningar orsakade av v\u00e4xlingsverkan, blixtnedslag och elektromagnetiska pulser.<\/p>\n

Enligt IEC61643-11.<\/p>\n

Termisk fr\u00e5nkopplingsenhet.<\/p>\n

Skruvterminalanslutning.<\/p>\n

\n

Ans\u00f6kan:<\/strong><\/p>\n

Skyddar elektriska installationer mot direkta blixtnedslag och avleder motstr\u00f6m fr\u00e5n blixtnedslag som sprids fr\u00e5n jordledaren till n\u00e4tverksledarna.<\/p>\n

Enheten \u00e4r utformad f\u00f6r att anv\u00e4ndas mellan zon O och zon 1 (enligt IEC 62305-4 definition av \u00e5skskyddsomr\u00e5de).<\/p>\n

Kan anv\u00e4ndas f\u00f6r att skydda det trefasiga elsystemet.<\/p>\n

Saker som beh\u00f6ver uppm\u00e4rksammas n\u00e4r du installerar SPD:<\/strong><\/p>\n

Best\u00e4m urladdningsstr\u00f6mv\u00e4gen.<\/p>\n

Markera ledningarna som ger ett extra sp\u00e4nningsfall p\u00e5 enhetens terminal.<\/p>\n

M\u00e4rk PE-ledaren f\u00f6r varje enhet f\u00f6r att undvika on\u00f6diga induktionsslingor.<\/p>\n

En ekvipotentialf\u00f6rbindelse uppr\u00e4ttas mellan enheten och SPD.<\/p>\n

Anslut enheten under installationen enligt installationsschemat, d\u00e4r L \u00e4r faslinjen, N \u00e4r neutrallinjen och PE \u00e4r jordlinjen. Koppla inte bort enheten.<\/p>\n
