That's normal for this class — the panel enclosure provides the overall protection.
The headline motor-switching number is 29 A at 400 V in AC-4 duty — that's the severe inrush from plugging or inching a motor, not just running it. If your application involves frequent reversing or jogging, this is the rating that governs contactor life. For standard motor starting (AC-3), the contactor handles 15 kW at 400 V, and it's rated 18.5 kW at 500 V and 10 kW at 690 V. The AC-2 rating (slip-ring motor starting) is 15 kW at 400 V. Auxiliary contact ratings cover 24 V at 10 A, 60 V at 2 A, 110 V at 1 A, 230 V at 6 A, and 400 V at 3 A — enough for most control-circuit loads, but check your coil inrush if you're driving multiple contactors from one aux.
No UL or CSA marks are listed in the spec record, so verify local code acceptance if your panel requires those approvals.
Main circuit terminals accept solid wire from 2x 0.5 to 1.5 mm² up to 2x 0.75 to 4 mm², and stranded wire from 2x 0.75 to 25 mm². Minimum cross-section at 40 °C is 16 mm². That covers most panel wiring up to about 6 AWG.
