| Description de l'article | Overvoltage protection / photovoltaic overvoltage protection type 1+2 (b+c) according to EN 61643-11:2012 / po i 5 PV 1000V DC/12, 5KA is photovoltaic overvoltage protection type 1+2 (b+c) according to EN 61643-11:2012. It serves for protection of DC photovoltaic systems with operating voltage up to 1000V DC, with connection "y" (2+PE, for +, PE and -). Overvoltage protection is 3-POLE protection with enhanced withstand against failures of insulation against the earth. It is manufactured with remote signalization of operation state ( r version ). Mounting is on DIN rail TS35 MM. Usage as the 1ST level ( T1, coarse protection) in a 3-LEVEL overvoltage protection concept. Protective modules ROTABLE with respect to the base through 180°.PO i 5 PV 1000V DC/12, 5KA is photovoltaic overvoltage protection type 1+2 (b+c) according to EN 61643-11:2012. It serves for protection of DC photovoltaic |
