Frequently Asked Questions
What does Type 1+2 surge protection mean?
Type 1+2 surge protection combines the features of Type 1 (protection against direct lightning strikes) and Type 2 (protection against switching surges) devices, providing comprehensive surge defence in one unit.
Can this SPD be used in residential installations?
While primarily designed for industrial and commercial use, it may be used in residential settings if the system voltage and configuration are compatible and local electrical standards permit.
How do I know when to replace the SPD?
The device includes an indication system that shows green when operational. If the indicator is not green, it signals that the SPD needs to be replaced.
Is this SPD compatible with TT earthing systems?
Yes, it is compatible with TT systems but only provides protection on the line-to-neutral conductor.
