LY*-(D.C.B)2  4P power supply surge arrester

Product Description
LY*-(D,B,C)2series surge protective device(in short: SPD, alias: surge protector, surge arrester)is suitable for TN-S,TN-C-S,TT,IT etc. power supply system of AC*0/*0Hz,≤**0V, installed on the joint of LPZ1 or LPZ2 and LPZ3,it's designed according to IEC******1,GB****2.1, it adopts *5mm 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.

Product feature:

1. Could be replaced for the module not need power cut.

2. Maximum current of endure the lightning-stroke *5KA(8/*0µ).

3. Response times<*5ns.

4. The color of visible window shows operating status,white means normal,red means abnormal. 

Application Scope and installation Position

It's suitable for B,C,D grade lightning-proof,LY*-(D,C,B)2 series surge protective according to GB*****1.*****2,installed on the joint of LPZ1 or LPZ2 and LPZ3,usually installed in household distribution boards, computer equipment, information equipment, electronic equipment and in the socket box in front of control equipment or near the control equipment.
