Product Information:

Surge protection device for all types of low voltage electric and electronic equipment rated up to 48 volts (nominal).

Features:

  • Pluggable module
  • Visual fault signalling
  • Use on systems up to 48 volts

Benefits: Middle conductor separated from protective earth via GDT.

Standards: EN 61643-11 (Surge Protection Devices).

Application: Install close to protected equipment in low voltage power circuits.

More Information:

Where low voltage, data, and telecom lines enter and exit the building, they must also be included in the Lightning Protection System.

These include:

  • Electromagnetic shielding
  • Telephone lines
  • Data communication lines
  • Instrumentation, control, signaling lines
  • Coaxial lines for CCTV, TV, & antenna cables

Field-based electronic equipment also needs to be protected.
