Features
SPD Type 1+2 Surge arrester range - three phase
high discharge capability and without following
current - system (230/400 V)
•
Surge arresters, suitable for low-voltage applications,
to protect equipment against overvoltage by direct
lightning strike, induction overvoltage and
switching overvoltage
•
To be installed at the boundary of LPZ 0 - LPZ 1 zones or higher
•
Versions with combined high energy varistor
block and heavy duty encapsulated spark gap (GDT)
which eliminates leakage current and ensures
high discharge current
•
No follow current
•
Very low residual voltage
•
Low U
p
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, 36mm each pole
