Will weathershield accessories convert a standard ventilated indoor transformer into a UL recognized NEMA 3R outdoor rated transformer?

Yes for Enclosures 17D through 31D.
Square D low voltage ventilated indoor transformers have been evaluated by Underwriters Laboratories and comply with NEMA 3R requirements when a weathershield accessory is added. The transformer nameplate indicates the proper weathershield kit to install to obtain NEMA 3R rating.
