Surge Protection Device (SPD)
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
• “1+1” configuration: varistor + spark gap
protection (avoiding earth leakage current)
• Conforms to EN61643-11
7P.32.8.275.2003
• Provides easy additional surge protection for
230V sockets
• Acoustic indication of need to replace varistor
• 3-wires, 150mm long, for connection to socket
terminals
7P.37.8.275.1003
• Permits serial connection for optimized load
protection up to 16A
• Integrated remote signalling contact of varistor
status
• Relay with gold change-over contact for
reliable low level switching
• 17.5mm L-N/N-PE protection
• Mounting on 35mm DIN rail (EN60715)
