Where it sits in the control system
The LV426251 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 25 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.
