Material:
Can be customized according to the customer’s requirements of any specification for your original product.
Function:
Parallel Modular Power SPD is designed according to the IEC Standard. The maximum discharging currents (IMAX 8/20µs) of each line could be 20-60kA. It is applicable for 220/380V Power Distribution System lightning protection in all classes.
This product adopts modular design with good tightness, working indictor, remote connector and degradation indicator. With 35 mm Electrical Lead Rail, it is convenient for connecting. With temperature control breaker, build-in over currents fuse protector and thermal inductance breaker, degradation automatic release. With advantage of extremely low residual Voltage, quick respond, large intake capacity, long working life, simple maintenance.
DK Company can manufacture various products with different working Voltage classes and lightning currents discharge capacity. And we also can produce the products completely according to the buyer’s requirement.
Supply Capacity:
We can produce 3000pcs with high quality per month.
Packing:
Usually be packed by carton box package. Also can be packed according to customer’s requirement.
