Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.

Where it sits in the control system

The LV426259 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 160 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.
