برق گیر 3 فاز تایپ 2+1مدلABB OVR-T1-3N-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
