Product Description:

Surge Protective Device

 

1. Could be replaced for the module not need power cut.
2. Maximum currrent of endure the surge stroke 20kA(8/20μs).
3. Time of response<25ns.
4. The color of visible window shows operating status,green means normal,red means abnormal.
* LY1-D series Surge Protective Device SPD is suitable for TN-S. TN-C-S. TT. IT etc.power supply system of AC 50/60Hz,≤380V,installed on the joint of LPZ1 or LPZ2 and LPZ3,it 's designed according to IEC61643-1. GB18802.1,it adopts 35mm standard rail,there is a failure release mounted on the module of Surge Protective Device.When the SPD fails in breakdown for over-heat and over-current,the failure release will help electric device separate from the power system and give the indication signal,green means normal,red means abnormal,it 's also could be replaced for the module when has operating voltage.

*. It's suitable for D grade surge protection,LY1-D series Surge Protective Device according to GB188021.1-2002, installed on the joint of LPZ1 or LPZ2 and LPZ3,usually installed in household distribution boards,computer equipment,information equipment,electronic equip ment and in the socket box in front of control equipment or near the control equipment.
*.Notice:When you order our goods,please write the model and quantity carefully.For example:LY1-D20/2-275,100 pieces.
