D Link 24 Port Patch Panel

Product Description

SPD is designed to limit transient overvoltages of atmospheric origin and divert current waves to earth so as to limit the amplitude of this overvoltage to a value that is not hazardous for the electrical installation and electric switchgear and controlgear

SPD eliminates over voltages

• in common mode between phase and neutral or earth
• in differential mode between phase and neutral

In the event of an overvoltage exceeding the operating threshold the SPD

• conducts the energy to earth in common mode
• distributes the energy to the other live conductors, in differential mode.

The three types of SPD

Type 1 SPD

The Type 1 SPD is recommended in the specific case of service sector and industrial buildings protected by a lightning protection system or a meshed cage

It protects electrical installations against direct lightning strokes It can discharge the back current from lightning spreading from the earth conductor to the network conductors

Type 1 SPD is characterized by a 10350 us current wave

Type 2 SPD
