Product details

Part overview and key ratings

The Schneider LC3D320AE7 is a TeSys D star delta starter, pre-wired with 3 x 3P (3 NO) power pole contacts, rated for 32 A in AC-3 utilisation category for motor control. IP20 front face protection suits enclosure-mounted installations where the panel door provides the outer seal.

Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D, with protective treatment TH per IEC 60068-2-30 for damp heat. Mechanical robustness includes vibration resistance of 2 Gn (contactor open) and 4 Gn (closed) over 5 to 300 Hz, and shock resistance of 15 Gn for 11 ms (closed) and 8 Gn for 11 ms (open). Fire resistance at 850 °C conforms to IEC 60695-2-1, and flame retardance is V1 per UL 94.

Frequently asked questions

What is the utilisation category and what does it mean?

The LC3D320AE7 is rated AC-3, which is the standard category for squirrel-cage motor starting and switching off during running. The 32 A rating applies under this duty, meaning it handles motor inrush and running currents within that limit.

What is the coil voltage and contact configuration?

The coil is 48 V AC. The power pole contacts are 3 x 3 NO (normally open), configured as a 3 x 3P star delta starter.
