Surge Protection Device (SPD)
SPD Type 1+2 Surge arrester range high
discharge capability with no following
current- single/three phase systems
• 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
• Versions with combination of varistor 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
7P.09.1.255.0100 SPD Type 1, GDT protection for
N-PE application only, for 3+1
configuration
7P.01.8.260.1025 SPD Type 1+2, varistor + GDT
unipolar protection suitable to
realize single phase or three phase
systems (230/400V) with the GDT
protection module (7P.09)
7P.02.8.260.1025 SPD Type 1+2 for single phase TT
and TN-S system. Varistor + GDT
protection L-N + GDT protection
