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 61643-21 (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.
A lightning surge protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment.
These include:
- Electromagnetic shielding
- Telephone lines
- Data communication lines
- Instrumentation, control, signalling lines
- Coaxial lines for CCTV, TV, & antenna cables
Field based electronic equipment also need to be protected.
