The 1- and 3-pole OutdoorDisconnectors FTr areapplicable for a rated voltage range of 12 kV to 38,5 kV and a rated current range from 630 Ato 4000 A. The rated short time current upto 50 kAfor a duration of 3s depending on the type has been tested. The 3-pole > Installation can be carried out at heights of up to 1000 m above sea level. At heights above 1000 m the rated insulating level of the switch must be cor- rected accordingly. The switches are designed for normal operating conditions according to IEC 62271-1.According to this the following limiting values applies:Ambient temperature: Peak...
