Category articles

The service life of LED lighting fixtures is a very important parameter. Urban authorities strive to exchange traditional lighting with LED lighting with the best technical and economical parameters.


The BLT series Phoenix Contact surge arrester is great for industrial LED luminaires in places like streets, tunnels, halls, warehouses, and parks.

BLT-T2 surge arrester is easy to connect to provide clamps that can be connected as a branch and through connections. They provide fault indication by turning off the LED luminaire and status indicator. The solutions used in the surge arrester effectively extend the life of the LED lamp. Combining parameters from Type 2 and 3 type delimiters with 5 kA 8/20 current output for a low level of protection provides the significant improvement in LED life.


Surge arrester can be used in devices with insulation classes I and II. The small size of the BLT-T2 surge arrester and elliptical holes allow for downsizing in assembly.

Main parameters of BLT-T2:

  • the degree of protection: IP20,
  • operating temperature: -40 ° C – 80 ° C,
  • power supply: TN-S,
  • class IEC: II / III,
  • protection class: I,
  • nominal voltage Un: 100 V AC – 277 V AC (TN-S),
  • rated load current: 16 A,
  • total discharge current: 20 kA.
