Surge Protection Device (SPD)
SPD Type 2+3 with combination of coarse and
fine suppression for 2 wires telecomunication
and signalling network
• Suitable for the protection of 2 wires data lines
and telecommunication interface allowing
continuity of the shield
• Permits serial connection optimizing the fine
protection of longitudinal overvoltage
(core-PG) and lateral overvoltage (core-core)
• Conform to EN61643-21+A1,A2:2013,
ENIEC61643-21+A1,A2:2012 C2,C3
• DIN rail mounting
7P.62.9.009.0485
• Suitable for the protection of RS485 data
lines of inverter, PLC, energy meters or other
interfaces
7P.62.9.036.0005
• Suitable for the protection of fire detection
systems, telecommunications interfaces and
2-wire data lines
7P.62.9.009.0485 7P.62.9.036.0005
• SPD Type 2+3
• Protection of RS485 data lines,
telecommunication and other Bus lines
• SPD Type 2+3
• Protection of fire detection systems,
telecommunication and other data/Bus lines
