Ambient temperature derating, IP55
IP55 (UL Type 12) drive types, other than the exceptions listed in the following
subheadings
In the temperature range +40…50 °C (+104…122 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F). The output current can be calculated by
multiplying the current given in the rating table by the derating factor (k):

IP55 (UL Type 12) drive type -045A-4
In the temperature range +40…45 °C (+104…113 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F). In the temperature range +45…50 °C
(+113…122 °F), the rated output current is derated by 1.5% for every added 1 °C
(1.8 °F).

IP55 (UL Type 12) drive type -293A-4
