Part Identification and Status
The Schneider Electric LC3D115V7 is a TeSys D star delta starter, pre-wired, with 3 x 3P (3 NO) power poles rated for 115 A. The coil is 400 V AC. Per the manufacturer's lifecycle record, this order code is classified as Obsolete.
Rated for utilisation category AC-3, which is the standard for squirrel-cage motor switching — starting, stopping, and inching under load. The 115 A rating applies to this duty, so it is sized for motor loads drawing up to that current during start. The IP20 front face protection means it is suitable for installation inside an enclosure where the front is operator-accessible but the live terminals are behind a panel door. Pollution degree 3 (conductive pollution) is the typical industrial environment assumption; no additional derating is required for normal factory floor conditions. The ambient air temperature for operation is -40 to 60 °C, with derating required above 60 °C up to 70 °C. Storage range is -60 to 80 °C. Operating altitude is rated to 3000 m without derating. Mechanical robustness is specified: vibrations at 2 Gn (contactor open) and 4 Gn (closed), shocks at 6 Gn (open) and 15 Gn (closed) for 11 ms. These figures confirm suitability for applications with moderate vibration, such as conveyor drives or pump skids. Fire resistance is 850 °C conforming to IEC 60695-2-1, and flame retardance is V1 per UL 94. Protective treatment is TH conforming to IEC 60068-2-30, meaning it is treated for tropical heat and humidity conditions. These compliance markers are relevant for tender submissions requiring documented material flammability and environmental protection.
