FAQ

• What does the SPD protect against?

It protects electrical equipment from transient overvoltages caused by lightning strikes, power grid switching, and other electrical surges.

• How do I know if the SPD is working properly?

The green indicator windows on the front of the device show the operational status. A green light means normal operation; red or no light indicates a faulty module that needs replacement.

• Can this SPD be used for single-phase systems?

This is a 3-pole model designed for three-phase systems. For single-phase applications, please choose a 1P or 1P+N SPD model.

• How often should I replace the SPD?

SPDs have a limited lifespan and should be replaced if they show abnormal status indicators or after being subjected to severe surge events. It is recommended to inspect them annually.
