برق گیر 3 فاز تایپ 2+1مدلABB OVR-T1-4L-25-255-TS

- Surge arresters, suitable for low-voltage applications, to protect equipment against overvoltage by direct lightning strike, induced overvoltage and switching overvoltage - To be installed at the boundary of LPZ 0 - LPZ 1 zones or higher - Combined high energy varistor block and high-performance spark gap (GDT) ensures: -high discarge current - high insulation resistance that eliminates leakage current -no following current - Very low residual voltage - Replaceable modules - Upside down mounting possible thanks to dual terminal markings and new restraint system for the replaceable module that permits its inversion - Visual fault signalling: Healty/Replace - Double screw terminal - Remote status signalling contact: Healty/Replace/Presence. Connector 07P.01 included - According to EN 61 643-11 - 35 mm rail EN 60715 mounting, 36 mm each pole
