Its AC-2 rating of 15 kW at 400 V covers slip-ring motor duty, while the AC-4 rating of 29 A at 400 V handles reversing or inching applications where the contactor makes and breaks stalled-rotor current.
Main circuit uses screw-type terminals; solid wire accepts 2x (0.25... 2.5 mm²), stranded accepts 2x (0.75... 25 mm²).
The substance prohibitance date of 05/01/2012 aligns with RoHS compliance — the part is RoHS-compliant as manufactured after that date.
The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance. It is designed for pollution degree 3 per IEC standards.
