Where it sits in the control system
The LV426223 is the device-level element in a Schneider Electric circuit breaker installation. It receives the field signals and control supply listed above — up to 690 V AC — and switches or conditions the load within the 40 A ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in distribution boards, motor protection circuits, panel feeders, where the unit is matched to the original catalog number and the enclosure provides By screws (plate) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Schneider Electric LV426223
Schneider Electric LV426223 — Circuit breaker providing branch-circuit overload and short-circuit protection in distribution boards and panel feeders. The figures below are taken from the specification table on this page for catalog number LV426223; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Degree of protection: IP40 — Use it as the reference when cross-checking a current-production equivalent.
- Operating temperature: -25...+70 °C — Verify it in the project documentation before confirming the order.
- Rated current Ie: 40 A — Check this value against the nameplate of the installed unit before ordering.
- Rated operational voltage: up to 690 V AC — Match it to the existing panel and upstream protection.
For a discontinued unit, match function and electrical ratings rather than the label alone.
