How do I select the right SPD for a single-phase installation?

When selecting an SPD for a single-phase system, consider:

• Voltage Rating: Ensure the SPD’s voltage rating matches the system voltage (typically 230V in the UK).
• Maximum Discharge Current (Imax): This indicates the surge current capacity the SPD can safely handle.
• Response Time: Look for an SPD with a fast response time to quickly divert surges before they can damage connected equipment.
