Schneider 7400WS18M19M – Frequently Asked Questions

1) What does the Square D 7400WS weathershield actually do to an enclosure?
It converts a standard indoor-rated Square D transformer enclosure to a NEMA 3R weatherproof rating. The shield bolts on over the enclosure and sheds rain and sleet so the equipment can be mounted outdoors. It is an enclosure accessory only, not an enclosure or a switch itself, so you still need the transformer enclosure it mounts to.
2) How do I pick the right 7400WS weathershield for my enclosure?
Match it to the enclosure number stamped on your Square D transformer enclosure. Three are offered: 7400WS18M19M for enclosure numbers 18 and 19, 7400WS20M for number 20, and 7400WS22M for number 22. The shields are sized per enclosure, so ordering by enclosure number is the only way to get the right fit.
3) Can I add the 7400WS weathershield to a transformer enclosure that is already installed?
Yes. The 7400WS mounts bolt-on, so it attaches mechanically to the existing enclosure rather than requiring a replacement housing. That means an indoor transformer enclosure already in service can be field-converted to NEMA 3R without pulling the unit, and the shield can be unbolted later for maintenance access.
4) Will the 7400WS weathershield fit a safety switch or a panelboard?
No. This weathershield is built for Square D transformer enclosures and is sized by transformer enclosure number (18-19, 20, 22). For a safety switch or panelboard you need a NEMA 3R enclosure or a shield made for that specific product line. Fit is determined by the enclosure number, not by the general size of the box.
5) Does the 7400WS weathershield meet environmental and RoHS requirements for a government or institutional spec?
It is RoHS compliant with exemption information on file, free of Substances of Very High Concern under REACH, mercury free, and free of toxic heavy metals. It is manufactured in the United States, which matters where domestic-origin sourcing is part of the specification.
6) What does a NEMA 3R rating actually protect against outdoors?
NEMA 3R covers outdoor use against falling rain, sleet, and ice formation on the enclosure. It is not a washdown or dust-tight rating, so for hose-directed water or heavy airborne dust you want a 4 or 4X enclosure instead. The 7400WS gets a standard transformer enclosure to that 3R level of protection.
7) Is the 7400WS weathershield a repairable part, or do I replace the whole shield if it gets damaged?
It is not a serviceable item. There are no field-replaceable subcomponents, so a shield damaged by impact or corrosion gets swapped out for a new one of the same enclosure number. Because it bolts on, the swap is a matter of removing fasteners rather than disturbing the transformer enclosure.
