برق گیر 3 فاز تایپ 2+1مدلABB OVR-T1-3N-25-255 قابلیت
SPD Type 1+2 - 3 x combined varistor and encapsulated spark gap + 1 encapsulated spark gap - Upside down mounting position
- 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
