29450 breaker status auxiliary contact: verified reference and application checks
29450 is a Schneider Electric reference for breaker status auxiliary contact. The shared main image illustrates the relevant category, not the exact 29450 item. The full manufacturer code should be the purchasing and receiving reference; visual similarity alone is not a compatibility test.

What to verify before ordering
Start with the installed nameplate or packaged label for 29450. Record the complete code, quantity, location and equipment revision. For 29450, check the electrical and mechanical ratings shown in the verified record, then compare them to the actual circuit duty and the applicable manufacturer installation instructions.
Request the exact reference, manufacturer documentation, accessory list, lifecycle/stock status and a written statement of any substitution.
A quotation for 29450 should distinguish a new original component from a surplus or repaired unit. Ask for the exact 29450 marking on the offered product. Where an older reference is no longer marketed, an alleged successor requires an explicit fit and protection review before approval.
Physical and electrical fit
Confirm the enclosure, rail or panel mounting, terminal access and available clearances for 29450. A number on a list does not establish terminal orientation, pole arrangement, wire size, fuse type, or trip-unit pairing. Verify the exact configuration of 29450 against the existing assembly, not against a nearby catalogue number.
For switching and protection items, check voltage, current, breaking or sensing duty and coordination with upstream and downstream equipment. For the metering and control versions of 29450, confirm sensor, wiring, supply and output details. Only the properties stated in the table above are treated as documented for 29450; any unlisted value remains to be checked.
Receiving and commissioning sequence
- Match the delivered designation with the purchase order and inspect packaging.
- Confirm documented ratings and the intended installation point.
- Install under the site isolation procedure and manufacturer instructions.
- Record the acceptance test, settings and final equipment tag.
Before fitting 29450, preserve settings, drawings and photographs of the original arrangement where relevant. Commissioning should test the actual function of 29450 in its installed context. A part that looks correct may still have a different rating, contact state, release voltage or protection characteristic.
Similar-looking catalogue references
The following 1 source-list codes share the visible 294 prefix with 29450. They are grouped for search and enquiry only. They may serve different functions and are not claimed to be interchangeable with 29450; check every complete code separately.
Decision note
Release 29450 for purchase only after the code, documented identity, installation duty and supplier offer agree. Keep 29450 in the order and acceptance record. Any proposed substitute should be evaluated separately rather than silently changing the reference.
Other visually similar numeric references
These references have the visible 29 prefix and are included for search and enquiry. They are not claimed to share this product function, ratings or dimensions and are not interchangeable. Confirm the exact full designation and manufacturer documentation for each number.
