Product Description
Product Introduction
Parallel Box-type power surge protector with thunder strike counter is designed according to the IEC standard. It is combined with working indicator, malfunction indicator and thunder strike counter.

This product is suitable for lightning protection of 220/380V electrical distribution system. It is adopted temperature control circuit break technology, built-in over-currents protector, that can avoid fire danger. It takes the advantage of low residual voltage, quick respond, large discharging capacity, long life, easy maintain etc. This product uses 3+1 protection mode. It's a SPD with different working currents levels and different discharging capacities.
8/20us Maximum Discharging Currents Imax can be 80-150kA/line.


Dikai company can produce the product according to the customer's special requirements.
