The 48 V AC coil suits control circuits running at that voltage. Flame retardance is V1 per UL 94, and the housing withstands 850 °C glow-wire testing per IEC 60695-2-1, which matters for panel builders needing compliance with fire-resistance requirements in industrial control panels. If you need a current-production star delta starter in the TeSys D family, the closest functional equivalent would be a combination of individual contactors and a timing relay — but that changes the form factor and wiring. For a direct drop-in, your best option is to source this exact obsolete code through the secondary market. The pre-wired design saves panel space compared to wiring three separate contactors — it's a single DIN-rail or screw-mounted unit with the interconnections already made. The IP20 front face means it's suitable for enclosed panels where the door provides the environmental seal. Pollution degree 3 rating confirms it handles conductive pollution typical of industrial environments. The 48 V AC coil draws from a control transformer or dedicated supply. Verify your control voltage matches exactly.","metaTitle":"Schneider LC3D120AE7 TeSys D Star Delta Starter, 12 A, 48 V","metaDescription":"Obsolete Schneider TeSys D LC3D120AE7 star delta starter. 3 x 3P (3 NO), 12 A AC-3, 48 V AC coil, IP20.
