XB5AC21 field record for Harmony XB5 mushroom pushbutton selection
The XB5AC21 designation identifies a Schneider Electric Harmony XB5 mushroom pushbutton. This field record puts the confirmed XB5AC21 facts first, then the checks needed to release an order. The reused main-image collage is a category reference, not a photograph of the exact XB5AC21 unit.

01 — Define the existing installation
Record the installed XB5AC21 label in full, the equipment tag, and any serial number, firmware or mechanical revision relevant to the assembly. A partial XB5AC21 designation does not establish compatibility.
Identify the supply, load, mating part, terminals, environment and available space before specifying XB5AC21. Keep a photograph of the original label and the cabinet or machine drawing with the inquiry.
02 — Decide whether the reference fits
This spring-return button is not automatically an emergency-stop device.
Compare the XB5AC21 parameters above with the actual circuit or machine duty. If the previous item has a different suffix, contact set, rating or enclosure, the proposed XB5AC21 must be reviewed as an engineered change.
03 — Install and document the result
Only qualified personnel should fit XB5AC21 after site isolation. Preserve settings and software backups where they apply to XB5AC21; label wiring before removal and use current manufacturer instructions for the final connection.
Functional testing of XB5AC21 should cover the intended switching, signal, drive or protection response and any alarms. Record measured values and the final XB5AC21 designation. Safety-related parts require validation of the complete function.
Similar-looking catalog codes
The 48 codes below resemble XB5AC21 through their XB5A pattern and are covered on this representative page. They are not separate pages in this publishing set. Similar code shape is not proof that a listed code can replace XB5AC21; compare the exact options and ratings.
Final release check
Before buying XB5AC21, confirm its current manufacturer datasheet, actual delivered nameplate, regional availability and any lifecycle notice. Retain the XB5AC21 technical review, accessory list and commissioning results for later maintenance.
