Medium-voltage disconnect switch ES 24-20-2

short-circuit

The disconnectors ITr and FTr are applicable for a rated voltage of 12 kV, 24 kV, 36 kV and 38.5 kV and a rated current range from 630 A up to 4000 A. Higher rated currents on request. The rated short-time current up to 50 kA for a duration of 3 s respectively 1 s depending on the model has been tested. The described disconnectors are intended for currentless switching in medium-voltage switchgears. The earthing switches ES can be used for a rated voltage of 3.6 kV, 12 kV, 24 kV, 36 kV and 38.5 kV. Some earthing switches have a short-circuit making capacity and are specified with the electrical life E1. The electrical life E0 is specified for earthing switches without short-circuit making capycity. All switchgears are type-tested according to EN 62271-102. For each switch an instruction manual for transportation, mounting and putting into operation is enclosed.
