FAQ

What voltage ratings are available?
250V, 500V, 600V, 800V, 1000V, 1200V and 1500V DC.

What is the advantage of gel encapsulation?
Gel encapsulation helps improve moisture and corrosion resistance of the MOV, making the SPD more suitable for demanding PV and DC environments.

Can the module be replaced?
Yes. The plug-in protection module can be replaced separately without replacing the complete base.

Is it suitable for outdoor PV systems?
The SPD body is rated IP20, so it should be installed inside a suitable weatherproof distribution box or control cabinet for outdoor applications.
