Ratings that govern the real application
At 35 °C the rated current is 2 A; at 40 °C it derates to 1.9 A, at 45 °C to 1.85 A, at 50 °C to 1.8 A, at 55 °C to 1.75 A, and at 60 °C to 1.7 A — so in a warm enclosure the load must be reduced accordingly to avoid nuisance tripping. The DC side carries a 220 V rating; the AC supply can be connected as required, but DC polarity must be observed per the manufacturer's note. Touch protection is built in (IP20 with connected conductors), and the unit is sealable — useful for panel builders who need to lock settings after commissioning.
