19000 Acti9 Vigi NG125 add-on residual-current device: verified reference and application checks
19000 is a Schneider Electric reference for Acti9 Vigi NG125 add-on residual-current device. The shared main image illustrates the relevant category, not the exact 19000 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 19000. Record the complete code, quantity, location and equipment revision. For 19000, 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 19000 should distinguish a new original component from a surplus or repaired unit. Ask for the exact 19000 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 19000. 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 19000 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 19000, confirm sensor, wiring, supply and output details. Only the properties stated in the table above are treated as documented for 19000; 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 19000, preserve settings, drawings and photographs of the original arrangement where relevant. Commissioning should test the actual function of 19000 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 6 source-list codes share the visible 190 prefix with 19000. They are grouped for search and enquiry only. They may serve different functions and are not claimed to be interchangeable with 19000; check every complete code separately.
Decision note
Release 19000 for purchase only after the code, documented identity, installation duty and supplier offer agree. Keep 19000 in the order and acceptance record. Any proposed substitute should be evaluated separately rather than silently changing the reference.
