## In plain English

### What the equipment does

A relay uses an electrical input or measured condition to change its contacts or output. This lets one circuit pass a command or indication to another.

### A simple example

Use RM22JA21MR_3D_2D-front.DXF (revision 1.0) to insert the supplied editable drawing into your layout. The ZIP contains the unmodified RM22JA21MR_3D_2D-front.DXF.

### What the drawings help you do

Use RM22JA21MR_3D_2D-front.DXF (revision 1.0) to insert the supplied editable drawing into your layout. The ZIP contains the unmodified RM22JA21MR_3D_2D-front.DXF. Use RM22JA21MR_3D.stp (revision 1.0) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified RM22JA21MR_3D.stp.

### Before using this reference

- Match Schneider Electric Modular 1-phase current control relay, 8 A, 2 CO, 24…240 V AC/DC and the exact source filename shown above.
- The supplied model has approximate X × Y × Z bounds of 22.9 × 92.7 × 80 mm. These are source-model axes; mounting holes and installation clearances must come from the matching manufacturer sheet.
- The orthographic views are projected from the manufacturer 3D geometry. They are labelled separately from original dimensioned sheets and do not add manufacturer dimensions.
- The source was checked on 2026-11-11; recorded file revisions: RM22JA21MR_3D_2D-front.DXF — 1.0; RM22JA21MR_3D.stp — 1.0. Use Documentation & sources to check for a newer issue.
