It's rated 32 A at AC with a 30 mA residual trip and a C-curve tripping characteristic, so it handles motor and lighting inrush without nuisance trips while catching ground faults down to 30 mA. If your line has VFDs or switching power supplies, you'd need a Type A or F device instead.
The IP20 rating applies once the distribution board is enclosed and conductors are connected. Temperature derating is published: full 32 A at 30 °C, drops to 29.1 A at 40 °C, 27.8 A at 45 °C, 26.6 A at 50 °C, and 25 A at 55 °C.
