Protection against indirect lightning effects

 

SPDS FOR TELECOMMUNICATION AND SIGNALLING APPLICATIONS

Typical installation: in series with the signal/telecommunication circuit for equipment with "low resistability" according Recommendation ITU-T K.45 / "low surge immunity" according IEC/EN 61000-4-5

Features:

• SPDs with impulse ratings for categories D1, C2 and C3 (according to IEC/EN 61643-21).

• SPDs with common mode and differential mode protection against symmetrical and/or asymmetrical disturbances.

• SPDs with disconnecting means in case of accidential contact between the signal/telecomminication circuit and a power line (e.g. 230/400V a.c.) due to insulation faults.

• SPDs with integrated earth/protective ground connection via the 35 mm top hat DIN rail and by screwless spring type termination of the cable screen.

 

SPECIFIC SPDS WITH COAXIAL CONNECTORS

Typical installation: for the protection of TV switchboards, satellite antenna or wideband transmission equipment and remote systems.
Particularly suitable for applications with long coaxial cables which are exposed to electromagnetic interference.

Features:

• SPDs with type F connectors for the protection of antenna circuits used in civil applications.

• SPDs with BCN type connectors for CCTV circuits.

• SPDs with 7/16 M/F type connection for coaxial cables of antenna circuits and telecommunication systems (4 and 3G).

• SPDs with special connectors/connection can be supplied upon request.
