Product details

It provides three power poles, each with three normally open contacts (3 x 3P, 3 NO), and is pre-wired for straightforward panel integration. The IP20 front face protection (IEC 60529) means the front of the unit is touch-safe inside an enclosure, but the starter itself is not sealed against moisture or dust ingress — it belongs in a clean, dry control cabinet. Fire resistance to 850 °C (IEC 60695-2-1) and V1 flame retardance (UL 94) give it a solid safety profile for panel applications where arc or thermal events must be contained.

Mechanical robustness is specified for vibration (2 Gn open, 4 Gn closed at 5–300 Hz) and shock (10 Gn open, 15 Gn closed for 11 ms). These figures are adequate for fixed-mount panel applications but not for mobile or high-shock environments.

Frequently asked questions

What is the official replacement for the LC3D12AV7?

No official successor order code is provided in the lifecycle record. A parametric match from the TeSys D family would need the same 12 A AC-3 rating, 3 x 3P (3 NO) contact arrangement, and 400 V AC coil. Verify fit against the existing panel wiring before substituting.

What are the key ratings of the LC3D12AV7?

It is a 12 A star delta starter for AC-3 motor duty, with 3 x 3P normally open contacts and a 400 V AC coil. IP20 front face protection, operating temperature -40 to 70 °C, and altitude capability to 3000 m.
