IP55 (UL Type 12) drive type -210A-7
In the temperature range +40…45 °C (+104…113 °F), the rated output current is
derated by 3.5% for every added 1 °C (1.8 °F). The maximum temperature is 45 °C
(113 °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) types -0430A-3, -0414A-5 and -0271A-7
The maximum ambient temperature is 35 °C (95 °F).
 Altitude derating
At altitudes from 1000 to 4000 m (3300 to 13123 ft) above sea level, the derating is
1% for every 100 m (328 ft). If ambient temperature is below +40 °C (+104 °F), the
derating can be reduced by 1.5% for every 1 °C reduction in temperature. For a more
accurate derating, use the DriveSize PC tool. A few altitude derating curves are
shown below. For a more accurate derating, use the DriveSize PC tool.
