Product details

It switches motor loads in AC-3 duty, rated at 9 A, with a 110 V AC coil.

The 110 V AC coil means it's intended for control circuits fed from a 110 V AC supply — common in North American panel designs. The 3 x 3P (3 NO) power pole configuration provides three normally open poles per contactor, which is the standard arrangement for star-delta transition. Operating altitude of 3000 m without derating covers most installations; above that, the switching capacity must be reduced.

Vibration resistance of 4 Gn (closed contacts) and shock resistance of 15 Gn (closed) make it suitable for installations near rotating machinery or on mobile equipment. Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D, covering humid and salt-laden atmospheres.

Frequently asked questions

What is the closest replacement for the LC3D090AF7?

No official successor order code is recorded in the lifecycle data. To find a current-production equivalent, verify the coil voltage (110 V AC), current rating (9 A AC-3), and star-delta configuration against the current TeSys D catalog.

What are the key specifications of the LC3D090AF7?

It is a TeSys D star delta starter with 3 x 3P (3 NO) contacts, rated 9 A in AC-3 motor switching duty, with a 110 V AC coil. The front face is IP20 rated.

What compliance documentation is available for this part?

The part carries fire resistance to 850 °C per IEC 60695-2-1, UL 94 V1 flame retardance, and climatic withstand per IACS and IEC 60947-1 Annex Q category D. It is rated for pollution degree 3.
