Frequently Asked Questions:
What does a Type 2 SPD do?
A correctly selected Type 2 SPD helps limit transient overvoltages. It cannot prevent every surge or guarantee that connected equipment will never be damaged.
Is this SPD suitable for residential use?
A qualified installer must confirm the SPD voltage rating, earthing arrangement, protection coordination and suitability for the distribution board. The 275 V UC marking alone does not establish suitability for every residential system.
What conformity documents should I check?
Check the exact model’s Declaration of Conformity and supporting documentation for its applicable standards. A CE mark is a declaration of conformity, not an independent test certificate.
Where should I install this SPD?
Have a qualified electrician select and install the SPD in a compatible distribution board, following the manufacturer’s instructions for connection length, earthing and backup protection.
