China Manufacturers CNKA offers AC power surge protection devices in stock that are designed to withstand significant discharge currents and maintain residual voltage at levels (Ures) below the peak voltage that the equipment can handle. In most cases, relying on a single SPD is insufficient, especially since surge intensity is unpredictable and overvoltage may occur when conductor lengths exceed 10 meters.
The optimal protection strategy is the 3-STEP method, which combines high-capacitance devices with low-performance devices that provide the best voltage protection. This approach addresses the varying types of transient pulses received in different protection zones by appropriately defining the SPD type used in each zone.

Q: When should SPDs be used?
A: CNKA Surge Protective Devices (SPDs) should be employed to protect the electrical infrastructure, including consumer units, wiring, and related components, from electrical surges caused by transient overvoltages.
Q: Are DC and AC fuses the same?
A: No, DC fuses are designed differently from standard AC fuses and incorporate additional components for effective arc extinguishing. The rated voltages for AC and DC fuses also differ, with DC fuses being considered more advanced due to their complex design.
Q: Can I get a sample before placing a bulk order?
A: Absolutely! We are happy to provide samples for quality testing, and we also welcome mixed sample requests.
