The LV426305 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 63 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.
Schneider Electric LV426305 — 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 LV426305; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Q.For LV426305, what does the specification table state about rated operational voltage?
The specification table lists rated operational voltage = up to 690 V AC for Schneider Electric LV426305. Use the value as the reference when sourcing a current-production equivalent.
Q.Which value is published under rated insulation voltage Ui for catalog number LV426305?
For LV426305, rated insulation voltage Ui is given as 750 V AC conforming to IEC 60947-2. Check the revision of the installed unit if the catalog number has been superseded.
Q.Before ordering LV426305, which rated impulse withstand Uimp entry should be checked?
The rated impulse withstand Uimp entry quoted above is 8 kV conforming to IEC 60947-2. Compare it with the nameplate of the installed unit before ordering.
Q.Can the LV426305 replace the unit currently installed in my panel?
Compare catalog number LV426305 and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
Q.How do I confirm compatibility of LV426305 before ordering?
Match the catalog number LV426305 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
