Part identity and key ratings
The LC3D80M7A64 is a TeSys D star-delta starter from Schneider Electric, pre-wired for motor starting applications. It carries three power poles in a 3 x 3P configuration (3 NO contacts) rated for 80 A in AC-3 utilisation category, meaning it switches three-phase induction motors up to that current during start and run. The coil is wound for 220 V AC.
Lifecycle and sourcing reality
This part is marked obsolete by the manufacturer. No official successor order code is listed in the lifecycle record. For a line-down or BOM-fill situation, the unit is sourced through surplus and broker channels against an RFQ — expect to specify the exact 220 V AC coil voltage and 80 A AC-3 rating when requesting quotes.
What the ratings mean for fit
The 80 A rating is under AC-3 duty, which covers starting and switching off squirrel-cage motors — the real-world load for this class. Pollution degree 3 means it's rated for industrial environments with conductive pollution, so it suits control panels without sealed enclosures. The IP20 front face protects against finger contact but not water ingress; mount it inside a cabinet rated for the site's washdown or dust requirements. Operating temperature spans -40 to 140 °F (-40 to 60 °C) with derating allowed up to 158 °F (70 °C). Storage range is wider at -76 to 176 °F (-60 to 80 °C). The TH protective treatment per IEC 60068-2-30 means it's treated against tropical humidity — relevant for coastal or unconditioned storage. Mechanical robustness is specified: 2 Gn vibration (5-300 Hz) with contacts open, 3 Gn with contacts closed; shock rated at 8 Gn for 11 ms open, 10 Gn closed. This matters for installations on vibrating machinery or near heavy impact loads. Fire resistance meets 1562 °F (850 °C) per IEC 60695-2-1, and the housing material is UL 94 V1 rated for flame retardance. Operating altitude is rated to 3000 m without derating.
Deployment context
This star-delta starter is designed for motor control panels where reduced inrush current during start is needed — typically for pumps, fans, and compressors up to 80 A motor FLC. The pre-wired assembly simplifies panel wiring, but the IP20 front face means it belongs inside a locked or tool-accessible enclosure.
