CJ-T2-40 385V 20-40ka 3p+N Lightning Surge Protective Device SPD

Producet Description CJ-T2-40 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 lEC61643-1,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 break down 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 is also could be replaced for the module when has operating voltage. Application Scope and Installation position CJ-T2-40 series surge protective device applied in C grade lightning-proof,installed on the joint of LPZ1 or LPZ2 and LPZ3,usually installed in household distrbution boards,computer eauipment information equipoment,electronic equipment and in the socket box in front of control equipment or near the control equipment.
