It carries 11 kW at 500 V and the same 11 kW at 690 V under AC-3 duty, which means it handles standard squirrel-cage motors up to those ratings without derating for the higher voltage. For AC-2 duty (slip-ring motors, resistive loads) it still delivers 11 kW at 400 V.
Main circuit terminals are screw-type, accepting solid conductors from 2x 0.5 mm² up to 2x 4 mm², and stranded conductors from 2x 1 mm² up to 2x 10 mm² (or 1x 8 AWG). That covers most panel wiring from control circuits up to motor feeders. The IP20 front protection means accidental finger contact is blocked, while the terminals themselves are IP00 — standard for enclosed panels where the gland plate or cabinet door provides the environmental seal.
Auxiliary and control ratings
The contactor carries 3 normally-open main contacts (no NC main poles). For auxiliary switching, the control circuit ratings cover a range: 10 A at 24 V DC, 6 A at 230 V AC, 3 A at 400 V AC, and down to 0.3 A at 220 V DC. The 50 Hz rated control supply voltage is 110 V (with a tolerance of 0.8 to 1.1 times nominal). If you're using this in a 24 V DC control scheme, the 10 A auxiliary rating gives headroom for pilot lights, PLC inputs, or interlocking relays.
