Valid for 50 % on time and 50 % off time. If other data is required, contact your sales office.
2)
Above 40 ºC up to max. 60 ºC reduce the rated current with 0.8 % per ºC.
3)
When used at high alitudes above 1000 meters up to 4000 meters you need to derate the rated current using the following formula.
