ABB NEMA 3R Main Module Enclosure Endwall Panel, Without Knockout

The ABB NEMA 3R Main Module Enclosure Endwall Panel is a modular enclosure accessory engineered to close out the end of ABB main module enclosure assemblies. Supplied without knockout (W/O KO) for a clean, uncut surface, this endwall panel is built to a NEMA 3R rating, supporting enclosure configurations used in outdoor and other wet-location electrical installations. Because it ships without pre-punched openings, installers retain full control over where conduit entries and cable openings are field-drilled, which is especially useful on custom panel builds where opening placement varies from project to project. Each unit ships individually packaged 1 EA, making it easy for electrical contractors, panel shops, and switchgear integrators to stock exactly the quantity a given job requires without over-ordering.

Key Features

  • Main Module Endwall: Closes out the end of an ABB main module enclosure section, providing a complete, finished enclosure assembly rather than an open frame.
  • Without Knockout (W/O KO): Supplied as a solid, uncut panel, giving installers a clean surface to field-drill, punch, or fit exactly as the application requires.
  • NEMA 3R Rating: Supports enclosure configurations intended for outdoor and other wet-location electrical installations where rain and falling dirt protection matters.
  • Modular Compatibility: Designed to integrate directly with ABB main module enclosure systems for a consistent, code-compliant enclosure build from end to end.
  • Individually Packaged: Ships 1 EA per unit, simplifying ordering, receiving, and inventory management on the job site or in the panel shop.
  • Enclosure System Accessory: Functions as a companion component alongside other ABB main module enclosure sections, sidewalls, and accessories.

Why ABB?

ABB brings decades of electrical engineering expertise to its enclosure systems, and the Main Module Endwall Panel is built to complete that system with a consistent, code-compliant fit. Its NEMA 3R rating and solid, no-knockout construction give electrical professionals a reliable component for finishing out enclosure runs in both indoor and outdoor installations. Choosing genuine ABB enclosure accessories helps ensure proper fit, finish, and long-term performance across the full enclosure assembly, and keeps a modular enclosure system compatible and serviceable over time. For contractors and panel builders standardizing on ABB enclosure platforms, this endwall panel is a straightforward way to keep every section of the assembly matched to the same manufacturer and rating, without needing to source a mismatched substitute from another supplier.

ABB TMEWNK01 – Frequently Asked Questions

1) What does the ABB TMEWNK01 endwall panel actually do in an enclosure assembly?
It closes out the open end of an ABB main module enclosure section, turning an open frame into a finished, sealed assembly. Think of it as the cap on the end of a modular enclosure run. Model TMEWNK01 is the version supplied without knockout, so the panel arrives solid and uncut.
2) Can I use this ABB endwall panel on an outdoor enclosure?
Yes. The endwall is built to a NEMA 3R rating, which covers outdoor and other wet-location installations where rain and falling dirt protection matters. It holds that rating as part of the assembly, so the rest of the enclosure sections it mates to need to carry the same rating for the build to hold up.
3) Why would I order an endwall without knockouts instead of a pre-punched one?
Because you decide where the holes go. A solid panel lets the panel shop or the electrician field-drill or punch conduit entries and cable openings exactly where the build calls for, which matters on custom panels where opening placement changes job to job. If your conduit runs land in a standard spot every time, a pre-punched endwall saves labor. If they do not, the W/O KO version is the one you want.
4) I am adding a section to an existing ABB enclosure run. Do I need a new endwall?
Yes, if the section you are adding becomes the new end of the run. The endwall moves to the outside face of the last module. On retrofits and expansions the panel is what re-establishes the closed, NEMA 3R enclosure after you break into the original end. The W/O KO version gives you a clean surface to re-punch for conduit that may now enter at a different point than it did on the old end.
5) What is the ABB part number for the main module endwall without knockout?
TMEWNK01. That is the model and manufacturer part number for the NEMA 3R main module endwall panel supplied W/O KO. Quote that number if you are matching an existing ABB enclosure build so you do not end up with the knockout version by mistake.
6) How does the ABB TMEWNK01 endwall ship, one per box or in a carton quantity?
Each one ships individually packaged, 1 EA. You order the exact count a job needs rather than buying into a multi-pack, which is useful when a panel shop is closing out two or three sections and does not want leftovers on the shelf.
7) Is this ABB endwall panel suitable for switchgear and panelboard housings?
It is used on panelboard and switchgear housings, modular enclosure systems, and utility and process control enclosure assemblies. Typical buyers are electrical contractors, panel shops, and switchgear integrators finishing out an ABB main module build.
