The LC3D115P7A64 is a pre-wired TeSys Deca star-delta starter, rated for AC-3 motor-switching duty with 3×3P NO contacts, and now obsolete per Schneider. No direct replacement listed under TeSys Deca; source through surplus.
AC-3 utilisation means the contactor is designed for switching squirrel-cage motors: making and breaking currents up to several times the rated operational current. The 3×3P configuration (three NO power poles per phase) is specific to star-delta starting, reducing inrush on transition. Pollution degree 3 and IP20 front face (IEC 60529) indicate the device is intended for an industrial enclosure where conductive dust or occasional condensation may occur. TH protective treatment (IEC 60068-2-30) confirms it withstands damp heat cycles. Flame retardance V1 (UL 94) and fire resistance at 850°C (IEC 60695-2-1) are relevant for panel certification — no additional fuse or barrier needed for these aspects.
This star-delta starter is wired into MCCs or standalone panels for starting three-phase induction motors. The pre-wired format reduces field wiring time. Operating altitude is rated to 3000 m without derating; ambient operation from -40 to 60°C, with derating up to 70°C.
Sourcing & lifecycle reality
The LC3D115P7A64 is obsolete per Schneider. No direct replacement from Schneider has been recorded; verify any claimed equivalent by checking the nameplate and wiring scheme. Source through surplus or submit an RFQ for availability and lead time.
