It switches motor loads up to 4 kW across a wide voltage range (220–690 V AC, 50/60 Hz) and carries utilisation categories AC-3 (squirrel-cage motors), AC-4 (plugging/inching), and AC-1 (resistive). The 9 A rating at ≤440 V AC-3 is the headline figure for motor duty. The coil includes a built-in bidirectional peak limiting diode suppressor. The auxiliary contact is 1 NC, instantaneous.
The 4 kW motor power listings confirm the practical load range across common line voltages. The flame retardance rating V1 per UL 94 and Class 2 per NF F 16-101/102 means the housing meets rail and industrial fire-safety standards. Heat dissipation is 1.3 W — low enough that no special ventilation is needed in a standard IP2X enclosure, but worth noting if you are packing multiple contactors into a small panel.
The TeSys K form factor is 45 mm wide, 58 mm high, 57 mm deep. The built-in coil suppression saves a slot for a separate snubber.
