What this part is and what it does
The Schneider Electric LC3D80P5 is a TeSys D star delta starter, pre-wired for motor starting duty. It carries 3 x 3P (three normally-open power poles) rated at 80 A in AC-3 utilization category, meaning it is sized for switching three-phase induction motors during start-up transition from star to delta configuration. The 230 V AC coil is built into the assembly. This is a pre-wired device — the contactors and timing relay are factory-assembled and wired inside a single enclosure, saving panel wiring time. The front face carries IP2X protection (finger-safe), and the unit is rated for pollution degree 3 environments typical of industrial control panels.
Lifecycle and sourcing reality
The LC3D80P5 is marked Obsolete by Schneider Electric. No official successor order code is listed in the available records. For a BOM line that calls out this exact part, the sourcing path is the surplus and broker channel — quoted to order against an RFQ. There is no direct form-fit-function replacement from the current TeSys Deca range that carries the same pre-wired star delta configuration at 80 A with a 230 V AC coil; any substitution requires a panel re-design.
Environmental and mechanical ratings
Operates from -40 to 60 °C (derated 60 to 70 °C) and stores from -60 to 80 °C. Fire resistance is 850 °C per IEC 60695-2-1, with flame retardance V1 per UL 94. Protective treatment TH per IEC 60068-2-30 covers tropical humidity exposure. Altitude rating is 3000 m without derating. Mechanical robustness: vibrations 2 Gn (contactor open) and 3 Gn (closed) over 5–300 Hz; shocks 8 Gn for 11 ms (open) and 10 Gn for 11 ms (closed). These ratings matter for machine-tool or conveyor applications where the panel is mounted on the moving equipment.
