It delivers 4 kW at 380...400 V AC, 4 kW at 415 V AC, 4 kW at 440 V AC, 2.2 kW at 220...230 V AC, and 5.5 kW at 500 V AC, all 50/60 Hz. The coil is wound for 380 V AC, so the control circuit must match that voltage; no built-in transformer for other control voltages. This is a plate-mounted unit (not DIN-rail), sized 173 mm high × 86 mm wide × 98 mm deep — the footprint matters when retrofitting into an existing panel where the mounting holes are already punched for the LC4 family.
If you need a functional replacement, the closest match within the TeSys family would be a current-production DOL starter with the same 9 A AC-3 rating and 380 V AC coil, but the mounting pattern and terminal layout may differ — verify the physical fit before committing the BOM line.
The 9 A AC-3 rating is the motor-switching current, not the resistive (AC-1) rating — AC-3 covers starting and plugging of squirrel-cage motors, where the inrush can be 6–8× the rated current. The part is sized for a motor drawing 9 A full-load, so a 4 kW motor at 400 V or a 5.5 kW motor at 500 V fits within the thermal capacity. The 380 V AC coil means the control transformer or PLC output driving this starter must supply 380 V AC; a 24 V DC or 110 V coil variant would be a different order code. Plate mounting (not DIN-rail) means the starter bolts directly to a backplate or sub-panel. The 173 mm height and 86 mm width are the envelope — allow clearance above for arc-chamber venting and below for wiring ducts.
