7P SERIES
Surge Protection Device (SPD)
7P
SERIES
SPD Type 1+2 Surge arrester range- three
phase high discharge capability with no
following current- system (230/400V)
• 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 heavy
duty encapsulated spark gap (GDT) ensures high
discharge current and eliminates leakage 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, 36mm each pole
