1) Note derating curve ( Section 8.4.4 "Reduced output current due to mains voltage").
2) FLA – Full Load Current, maximum current for the entire mains voltage range as stated above (200 V – 240 V) according to UL/CSA
3) FLA (S1-40°C)
4) SK 21xE and SK 23xE devices: For use of safe functions (functional safety: STO and SS1) the restrictions regarding the permissible temperature
range according to BU 0230 must be noted.
5) Fan cooling, temperature-controlled: ON= 55°C, OFF= 50°C,
After-run time when 50°C limit undershot and enable removed: 2 minutes
6) Maximum permissible mains short circuit current
7) "Inverse time trip type“ according to UL 489
