Product details

The LC3D120AV7 is a TeSys D star delta starter from Schneider Electric, pre-wired with 3 x 3P normally open power poles. It's rated for AC-3 utilisation category at 12 A, with a 400 V AC coil — sized for motor control applications where reduced inrush during start-up is needed.

Sourcing & Lifecycle Reality

This order code is marked Obsolete by the manufacturer. No direct successor is listed in the official record. Verify the coil voltage (400 V AC) and the 3 x 3P NO pole configuration when evaluating any replacement.

AC-3 rating at 12 A means it's specified for starting and stopping squirrel-cage motors under load — the standard duty for star delta starters. Pollution degree 3 (conductive pollution) is the typical industrial environment rating, so it expects the panel to manage dust and condensation. The 850 °C fire resistance and V1 flame retardance (UL 94) are compliance marks for the enclosure material, not a functional spec.

Frequently asked questions

What is the closest alternative to the LC3D120AV7?

No official successor order code is listed. A replacement would need to match the 12 A AC-3 rating, 400 V AC coil, and 3 x 3P NO pole configuration of the TeSys D star delta starter.

What is the range and product name for this part?

It belongs to the TeSys range and is specifically the TeSys D product name.

What compliance documentation is available for the LC3D120AV7?

The part carries a fire resistance rating of 850 °C per IEC 60695-2-1 and a V1 flame retardance per UL 94. Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D. Protective treatment is TH per IEC 60068-2-30.
