Power Supply Surge Protective Device

Product introduction:

SDZ100-50 is class 1 switch-type surge protection. It can effectively release the incoming and inductive lightning on the low-voltage line of system, and effectively protect power supply equipment from lightning strike.

Characteristic:

1/ Impulse current reaches 10/350μs 60kA;

2/ Low voltage limitation;

3/ Nominal discharge current reaches 8/20μs 200kA;

4/ Strong capability to cut off residual current;

5/ Discharge monitor is applicable to configurate with RS485 communication.

Installation:

1/ Install on 35mm rail;

2/ It is necessary to series connect a fuse or air switch with SPD.

Maintenance:

SPD should be inspectied and maintenance in reuglar basis, pls duly replace SPD if it is red color in display window.
