The WSPDTE-2 is a 1P+N Type 1+2 AC surge protection device designed for single-phase incoming supplies where both lightning current discharge and transient overvoltage protection are required. It is typically specified on installations with external lightning risk, overhead supplies, or exposed locations.
By combining Type 1 lightning protection with Type 2 surge suppression, the WSPDTE-2 provides coordinated protection at the origin of the installation, helping prevent high-energy surge events from reaching downstream circuits and sensitive equipment. Its compact 36mm DIN rail footprint allows clean integration into single-phase consumer units and distribution boards.
Installer Tip: Ideal where a single-phase intake requires both lightning protection and downstream surge suppression in one device.

What is a Type 1+2 surge protection device used for?
Type 1+2 SPDs provide combined lightning current discharge and transient overvoltage protection, allowing them to be installed at the origin of the installation without requiring separate devices.
Is the WSPDTE-2 suitable for domestic installations?
Yes, where a lightning risk assessment specifies the need for combined Type 1 and Type 2 protection on a single-phase supply.
Where should this SPD be installed?
It should be installed as close as possible to the incoming supply terminals to minimise conductor length.
Which earthing systems are supported?
The WSPDTE-2 supports TT and TN earthing systems when installed correctly.
How much DIN rail space does it require?
The device occupies 36mm of DIN rail space, equivalent to two standard modules.
