FAQ

Frequently Asked Questions

What is the difference between Type 1, Type 2 and Type 3 SPDs?

Type 1 protects against direct lightning (service entrance), Type 2 against switching and residual surges (distribution boards), Type 3 for sensitive end-equipment. Our range centres on Type 2 AC and DC protectors.

What does the kA rating mean?

The kA figure is the maximum discharge current (Imax) the SPD can safely divert once, while In is the nominal rating for repeated surges. Choose based on your exposure level and local code.

Do you supply DC SPDs for solar?

Yes – we stock DC SPDs rated 500V–1000V for PV string and combiner-box protection, plus AC SPDs for mains distribution boards.

What is the MOQ for SPD orders?

MOQs are flexible per SKU to support mixed containers. Share your target quantities and we will confirm the best configuration.

Do you provide test reports?

Yes – IEC 61643-11 type-test reports and CE documentation accompany every shipment. Country-specific certifications available on request.
