Product Information:

Surge arrester for protection of LED lights.

Features:

  • Compact size
  • Fault signalling by supply interruption

Benefits: Simple installation in applications with limited space.

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

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

More Information:

Public lighting systems, street lighting for example, as well as lighting for large industrial premises, can be extensive, with cable lengths running into hundreds of meters.

Such systems are exposed to risks of overvoltages induced by lightning strikes, as well as switching events. Transient overvoltages in extensive installations may reach values that are higher than the specified withstand voltage of the light source (luminaire), thus leading to damage.
