Q&A
Q: What's the warranty for SPDs? No need to replace it all the time?
It is recommended to replace it per 3-5 years.
Q: How to purchase a suitable DC SPD from HYOCIE?
You have to assess the risk of lightning strikes and discharge capacities before purchasing. Usually customers purchase type 2, which is DC SPD T2 series, because it is used at distribution boards.
Q: If SPD fails, what will happen?
When an SPD fails, the MOV short-circuits. It must be disconnected from the system immediately. We recommend using a circuit breaker or an internal/external overcurrent fuse in front of an SPD.
