7P SERIES
Surge Protection Device (SPD)
7P
SERIES
SPD Type 3, Surge arrester for TT and TN-S
system (with Neutral)
Single phase applications within socket
outlets and 35mm rail mounting
• Protects electrical and electronic equipment
sensitive to impulse overvoltage
• Varistor and spark gap (GDT) combination
avoiding earth leakage current
• Conforms to EN61643-11:2012
7P.36.8.275.2003
• Provides easy additional surge protection for
230V sockets
• "Y" configuration: varistor + spark gap with very
low U
p
level
• Audible indication of need to replace varistor
and jumper test point for SPD status
• 3-wires, 150mm long, for connection to socket
terminals
7P.37.8.275.1003
• "1+1" configuration: varistor + spark gap with
very low U
p
level
• Permits serial connection for optimized load
protection up to 16A
• Integral CO contact for remote signalling of
varistor status - contact gold plated for reliable
low level switching
• 17.5mm L-N/N-PE protection
• Mounting on 35mm DIN rail (EN60715)
