The 24 V AC coil suits control transformers common in panel builds. This is a panel-mounted star delta starter, pre-wired to reduce installation time. The 3 x 3P NO pole arrangement covers the line and delta contactors in a standard star-delta circuit; the star contactor is typically the third pole set. Operating altitude is rated to 3000 m without derating, covering most high-altitude plant sites. Ambient operating range is -40 to 60 °C, with derating above 60 °C up to 70 °C. Storage range extends from -60 to 80 °C. Mechanical robustness is specified at 2 Gn vibration contactor open, 4 Gn closed, and shock ratings of 15 Gn closed for 11 ms — sufficient for most industrial machinery and conveyor lines. These ratings satisfy most panel builder and machinery safety audits without additional fire barriers. The AC-3 rating at 150 A is the motor-switching current, not the resistive (AC-1) rating. For a star-delta starter, the line and delta contactors each see roughly 58% of motor full-load current; this unit handles motors up to about 260 A FLC in star-delta configuration. The 24 V AC coil draw is typical for the TeSys D range — verify the control transformer VA budget includes coil inrush. Protective treatment TH per IEC 60068-2-30 means the unit is tested for damp heat cyclic conditions, suitable for non-condensing humidity in temperate climates. No additional tropicalisation needed for standard indoor panels.","metaTitle":"Schneider TeSys D LC3D150B7A64 Star Delta Starter, 150 A, 24","metaDescription":"Schneider TeSys D LC3D150B7A64 star delta starter. 150 A, 24 V AC coil, 3 x 3P NO.

A functionally similar unit would be the standard LC3D150B7 (same 150 A AC-3 rating, same 24 V AC coil) but not pre-wired as a star delta assembly. The pre-wired version saves panel wiring time; the standard version offers more flexibility for custom interlocking."},{"question":"What compliance documentation is available for this part?","answer":"The LC3D150B7A64 carries fire resistance to IEC 60695-2-1 at 850 °C and flame retardance V1 per UL 94.
