It combines a 32 A thermal-magnetic B-curve MCB with a Type F residual current device in a single 36 mm wide (2 MW) module. Type F means it detects AC pulsating and smooth DC fault currents plus high-frequency residuals from variable-speed drives and LED lighting, which standard Type A devices miss. Supply can land on either top or bottom terminals, and the unit mounts in any position inside an IP20 enclosure.
In a typical 40 °C panel, the continuous current drops to 30.4 A; at 50 °C it's 28.8 A; at 55 °C (the upper operating limit) it's 27.84 A. The maximum power dissipation is 11.4 W, which adds to the enclosure's thermal budget.
That top end (35 mm²) is oversized for a 32 A device — it allows looping through or tapping a larger feeder without a separate terminal block.
