What is the Ingress Protection rating for the Wiser Electrical Heat Switch?

IP44*
*IP 44 Ingress protection achieved in laboratory testing. Final IP rating is dependent on installation. For best results ensure a good seal exist between the rubber grommets, cable, and enclosure.

As an IP44 rating indicates that the product is splashproof, it's considered safe to use IP44 products in drier or more sheltered areas where they may be infrequently exposed to moisture, either indoors or outdoors.
