1)
All rated values refer to a mains input voltage of 400 V / 50 Hz and a control voltage of 24 V.
2)
Effective value at an environmental temperature of 40 °C.
3)
Between 40 °C and 55 °C the output current must be reduced.
The permitted output current (I
0
) is calculated with the following formula:
