Product Description

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 rlease 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.

Products features:

1. Three-phase protection for TN-S system

2. Pluggable module, easy for installation and maintenance

3. High discharge capacity, quick response

4. Double thermal disconnection devices, providing more reliable protection

5. Green window will change when fault and also provide remote alarm control at the same time
