Its AC-3 rating at 400 V is 5.5 kW, meaning it handles the high inrush of a standard induction motor during start-up. At 690 V it also carries 5.5 kW, so the motor current, not voltage, is the limiting factor here. For reversing or plugging duty (AC-4), it is rated 8.5 A at 400 V.
The contactor's auxiliary contact is a single instantaneous make/break (1 NO or 1 NC depending on variant — here it is a single contact block). For switching smaller loads on the auxiliary, the rated operating current at AC-12 (resistive) is 10 A maximum.

Mechanical service life is 30 million operations.
Wiring and terminations
Main current circuit terminals are screw-type, accepting solid or stranded conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or max 2x 0.75–4 mm². AWG equivalents are 2x 20–16, 2x 18–14, and 1x 12.
