• Rated currents Ir
630 A, 1600 A, 2500 A, 4000 A and 6300 A

The 1-, 2- and 3-pole Disconnectors ITr are applicable 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 kA for a duration of 3 s depending on the model has been tested.
The 3-pole Earthing Switches ES can be used for a rated voltage range of 12 kV, 24 kV, 36 kV and 38,5 kV.
A rated short time current of 20 kA and 31,5 kA is specified.
The described Disconnectors are intended for currentless switching in medium voltage switchgear.
All switchgears are type-tested according to EN 62271-102.
For each switchgear an instruction manual for transportation, mounting and commissioning is inclosed. This instruction manual should be
strictly followed. Refer to brochure 731e
