The AC-2 switching capacity at 400 V is rated at 4 kW, meaning the contactor handles wound-rotor motor loads up to that power level without contact welding. AC-4 at 400 V is 8.5 A, covering reversing or inching duty where the contacts make and break under full load. The 24 VDC coil holds reliably at nominal voltage; dropout below 18 V is typical for this class, so verify your control supply stays above that threshold.
The contactor measures 45 mm wide, 57.5 mm tall, and 72 mm deep, fitting the S00 footprint. The IP20 finger-safe enclosure on the front and terminals means the panel builder can work near live busbars without additional shrouding — standard for control cabinets.
Terminal and wiring
The screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a maximum of 2x (0.75 to 4 mm²) per clamp. AWG equivalents are 2x (20 to 16) solid and 2x (18 to 14) stranded, plus a single 12 AWG. Strip length is not stated in this record, but the S00 family standard is 8 mm — verify against the terminal marking before wiring.
