At 500 V it carries 22 kW, and at 690 V it's good for 11.4 kW. The AC-4 rating at 400 V is 35 A — that's the plugging / inching duty, which is harder on the contacts; if your application does reversing or jogging, that 35 A figure is the one you size against, not the AC-3 number. The auxiliary contact block on the front handles 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V — enough for a PLC input or a pilot light, but if you need more than one auxiliary circuit, you'll add a side-mount block. The coil operates at 50 Hz, 110 V rated value, with a pickup range of 0.8 to 1.1 times nominal — so it pulls in reliably even if your line voltage sags to 88 V.
It's 75 mm wide, 112 mm tall, and 115 mm deep — that's a Size S2 footprint, standard for this current class. Keep that in mind for the panel layout; you'll want the gland plate or a cover over the terminals if the enclosure gets opened live.
