Product application:
DTPS1-A series surge protection device (in short SPD,alias:surge suppressor surge arrester)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 protection device, When the SPD fails in breakdown for over heat and over-current, the failure release will help electric equipments separate from the power supply system and give the indication signal, green means normal, red means abnormal, it also could be replaced for the module when has operating voltage.
Product Features:
1、Inside over-current and over-heat protection, temperature control open circuit.
2、Module design, convenient installation, could be replaced online.
3、Time of response <25ns.
4、The color of visible window shows operating status, green means normal, red means abnormal.
