Disconnectors, Earthing switches, Fuse bases - 2

The 1-, 2- and 3-pole Disconnectors ITr are appli-cable for a rated voltage range of 12 kV, 24 kV 36 kV, 38,5 kV and a rated current range from 630 A to 6300 A. The rated short time current upto 63 kAfor a duration of 3 s depending on the model 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 switchgear must be corrected accordingly. The switches are designed for normal operating condtions according to IEC 62271-1.According to this the following limiting values applies:Ambient...
