Rittal WM121206NC – Frequently Asked Questions

1) Can a Rittal WM Series carbon steel enclosure be mounted outdoors?
Yes, within the limits of a NEMA 3R rating. The WM Series one-door wall mount enclosure is rated NEMA 3R, which covers outdoor, rain-protected service: rain, sleet, snow and falling dirt. It is not a washdown or hose-down enclosure, so if your location sees direct pressure spray or corrosive wet process areas, step up to a gasketed NEMA 4 or 4X type instead.
2) What sizes does the Rittal WM Series one-door wall mount enclosure come in?
Two sizes are offered: 12 x 12 x 6 inches (WM121206NC) and 24 x 24 x 8 inches (WM242408NC), both height x width x depth. The 6 inch depth on the small box is tight for anything with deep-bodied breakers or stacked terminal rails behind the door, so for a populated control panel the 8 inch deep 24 x 24 is the safer pick.
3) What is another NEMA 3R rated enclosure if the Rittal WM Series sizes do not work for the installation?
The ABB Q-Line NEMA 3R 225A enclosure is also NEMA 3R rated, and it is built around a 225A Q-Line load center application rather than as a general-purpose wall mount box. The Rittal WM Series is a NEMA 3R one-door carbon steel wall mount enclosure in sizes from 12 x 12 x 6 inch up to 24 x 24 x 8 inch, intended as open housing for panels, terminal blocks, and control devices. Choose the Q-Line unit when the enclosure has to suit that breaker assembly, and the WM Series when you are mounting your own components inside.
4) Is the Hoffman A12124GSC a direct substitute for a 12 x 12 x 6 inch Rittal WM enclosure?
Not a direct one. The Hoffman A12124GSC is a screw-cover gasketed enclosure measuring 12 x 12 x 4 inch, so the cover lifts off entirely and the depth is shallower. The Rittal WM121206NC is 12 x 12 x 6 inch with a single hinged door, which stays attached while you wire. If you need the extra two inches of depth for device stack-up, or want a door rather than a removable cover for repeated access, stay with the WM Series.
5) Is the Rittal WM enclosure steel or stainless, and how is it finished?
Carbon steel body with a powder coat finish in RAL 7035 gray. That holds up to impact and gives corrosion and scratch resistance for indoor and rain-protected outdoor mounting, but it is a painted steel box, not stainless. For a corrosive or food-plant environment specify stainless, such as the Eaton 10250T heavy-duty watertight/oiltight stainless steel enclosure.
6) Does the WM Series enclosure have a hinged door or a screw cover?
A single hinged door, so you can swing it open and leave it open while you terminate wiring or mount devices on the back panel. If you want a flat screw-on cover instead, that is a different build, like the Hoffman A12124GSC screw-cover gasketed enclosure at 12 x 12 x 4 inches. Hinged doors are generally preferred where the box gets opened for routine maintenance.
7) Is a NEMA 3R enclosure enough for a washdown area or outdoor meter location?
No. 3R protects against falling rain, sleet and snow but is not watertight against directed spray. For a hose-down bay or an exposed metering install, go to a NEMA 4X type such as the Square D EM3570ENC enclosure for PowerLogic EM357x meters. Keep the Rittal WM for sheltered exterior walls and indoor industrial spaces.
8) Can I use an Eaton M22 surface mounting enclosure in place of a Rittal WM enclosure?
No. The Eaton M22 one-element surface mounting enclosure is a non-illuminated 22.5 mm housing sized for a single pilot device such as a pushbutton or selector switch. The Rittal WM Series is a wall mount enclosure from 12 x 12 x 6 inch to 24 x 24 x 8 inch, sized to hold panels, terminal blocks, and control devices behind a hinged door. The M22 is an operator station, not a panel enclosure.
9) We need a washdown or corrosive-area enclosure instead of NEMA 3R. What else is there?
Two options in that direction: the Eaton 10250T heavy-duty watertight/oiltight enclosure is stainless steel with a 30.5mm device opening, and the Square D EM3570ENC enclosure for PowerLogic EM357x meters is NEMA 4X. The Rittal WM Series is NEMA 3R powder coated carbon steel, which covers rain-protected outdoor and indoor use rather than direct hosedown or chemical exposure. For a general wall-mount box in a sheltered location the WM Series applies; for a wet or corrosive room, look to the stainless or 4X rated units.
10) Will all the WM Series sizes match in appearance if I install several on one building?
They will. Every size in the WM one-door line uses the same carbon steel construction and RAL 7035 gray powder coat, so a 12 x 12 x 6 next to a 24 x 24 x 8 reads as the same family. That is useful for facility teams standardizing enclosures across multiple mounting locations.
11) What are the other general-purpose enclosure families to consider alongside the Rittal WM Series?
Two broader families come up: the ABB Formula A2ENCL250 Series surface-mount electrical enclosure and the Eaton MVXENC Series industrial electrical enclosure. The Rittal WM Series distinguishes itself as a NEMA 3R one-door design in RAL 7035 gray powder coated carbon steel, offered in 12 x 12 x 6 inch and 24 x 24 x 8 inch, so it is the one to specify when you want consistent fit and finish across wall mount locations in a facility.
