Rittal 1244250 – Frequently Asked Questions

1) Can a Rittal WM Series steel enclosure be mounted outdoors?
Yes. The Rittal WM Series wall-mounted enclosure carries NEMA 1, 3R, 4 and 12 ratings, so it's rated for outdoor and wet-location installs as well as indoor dust and drip protection. The seal comes from a foamed-in-place gasket working against a knife-edge sealing surface, with a secure locking system holding the door closed against it.
2) What sizes does the Rittal WM Series wall enclosure come in?
Four footprints are offered: 400 x 400 mm (part 1244250), 600 x 600 mm (8017536), 600 x 760 mm (1076250) and 760 x 760 mm (1077250). Sizes are given width by height. Pick the footprint off your component layout and the wall space you have, since all four share the same single-door, left-hinged arrangement.
3) Does the Rittal WM enclosure come with a back panel, or do I buy that separately?
A mounting plate is included. It's zinc plated steel at 2.5 mm thick, so you can drill and tap it for DIN rail, wireway or component mounting without adding a sub-panel. The enclosure also ships with the hinged door, rear wall mounting holes and the quarter turn latch already fitted.
4) What can I use instead of a Rittal WM enclosure if I only need outdoor rain protection for a 225A breaker?
For a straightforward 225A outdoor application, the ABB Q-Line NEMA 3R 225A enclosure is purpose-built around that breaker and carries a NEMA 3R rating. The Rittal WM Series steel wall-mounted enclosure is a general-purpose single-door housing rated NEMA 1/3R/4/12, so it goes beyond rain protection into washdown and dust-tight duty and ships as an empty box with a zinc plated mounting plate you lay out yourself. Choose the Q-Line when the breaker defines the box, and the WM when you are building a custom panel layout.
5) Is the Square D EM3570ENC a substitute for a Rittal WM enclosure?
Not generally. The Square D EM3570ENC is a NEMA 4X enclosure built specifically to house PowerLogic EM357x meters, so its interior is dedicated to that meter family. The Rittal WM Series is an open single-door steel enclosure with a zinc plated mounting panel and sizes from 400 x 400 mm to 760 x 760 mm, intended for whatever components you mount inside. If the job is a PowerLogic meter, the EM3570ENC is the matched housing; if the job is a control panel, the WM gives you the blank footprint.
6) I need a NEMA 4X enclosure for a corrosive area - will a Rittal WM work?
The Rittal WM Series is rated NEMA 1/3R/4/12 with a cold rolled steel body, which covers dust-tight and hosedown duty but is not a 4X corrosion-rated housing. Where 4X is specified, the Square D EM3570ENC is a NEMA 4X enclosure, though it is dimensioned around PowerLogic EM357x meters rather than a free-form panel layout. Confirm the 4X call-out on your drawing before substituting either way.
7) How heavy is the steel on the Rittal WM Series enclosure body and door?
Body is 1.5 mm cold rolled steel, the door is 2 mm, and the mounting plate is 2.5 mm zinc plated. The heavier door gauge is what keeps the leaf flat against the knife-edge and gasket so the NEMA 4 seal stays consistent over the full 760 x 760 mm size.
8) How do you open a Rittal WM enclosure, and can it be locked?
Access is through a quarter turn latch with a slotted head insert, so a screwdriver or standard latch key turns it. It isn't a keyed cylinder lock out of the box. For rooms where anyone with a flat blade can get at the panel, that's worth knowing up front.
9) Is a NEMA 4 steel enclosure right for a washdown or corrosive area?
The WM Series is painted cold rolled steel, which suits general indoor, outdoor and industrial control use under its NEMA 1/3R/4/12 ratings. Where you're dealing with chemicals, salt air or frequent caustic washdown, buyers usually step up to a NEMA 4X rated enclosure instead. The Square D EM3570ENC is a NEMA 4X option in our range, though it's built as a meter enclosure for the PowerLogic EM357x rather than a general-purpose wall box.
10) Do Rittal WM enclosures come with knockouts for conduit?
No. The WM Series body ships without conduit knockouts, so you make your own penetrations in the field and seal them with rated hubs or fittings to keep the NEMA 4 and 12 protection intact. That's normal for a sealed industrial wall enclosure and it's why the mounting plate is separate from the body.
11) How does the Rittal WM enclosure mount to the wall?
Through rear wall mounting holes in the back of the body, so it hangs flat against the wall or a structural surface with your own anchors. No external mounting brackets or feet are part of the package, and no floor stand is involved, this is a wall-mount box only.
12) How does the ABB CR Series enclosure compare to the Rittal WM Series for an industrial control panel?
Both are industrial housings for mounting control components. The ABB CR Series is an industrial electrical enclosure housing from ABB's CR line. The Rittal WM Series is a cold rolled steel wall-mounted enclosure with a left-hinged single door, foamed-in-place gasket and knife-edge sealing surface, rated NEMA 1/3R/4/12 and finished in RAL 7035, offered in four footprints from 400 x 400 mm up to 760 x 760 mm. If your specification calls out a metric footprint, a sealed gasketed door and a NEMA 4/12 rating on the same box, the WM Series matches that description directly.
13) What color do Rittal WM enclosures ship in, and will they match our existing panels?
RAL 7035, the standard light grey used across most industrial control panel work. If your plant already standardizes on RAL 7035 enclosures, these drop straight into that scheme with no repaint.
14) Is the Rittal WM Series a single door or double door enclosure?
Single door across all four sizes, up to the 760 x 760 mm. If your layout needs a double-door front for wider component runs, this family won't cover it.
15) What else could I use instead of a Rittal WM enclosure for a service disconnect?
The WM Series is a general-purpose wall box for control gear and panel builds, you populate the mounting plate yourself. If what you actually need is a rated enclosure sized around a specific breaker, the ABB Q-Line TQD225R is a NEMA 3R enclosure for a 225 amp application. The ABB CR Series is another industrial enclosure housing line in our range if you're comparing general-purpose options.
