The three-position switch RV 50 (ON/OFF/EARTH) is tested in accordance with IEC standards.
The concept ensures a natural interlock (Open, Closed, Grounded) of the primary functions of the cubicle. A short bow time by optimizing the speed of the mechanical drive and a patented combines with a SF6-gas rotation and electrical contacts for the extinction of the arc. Our experience with the RV 44 switch from the DF-2 range, finds a perfect application here. The switch is of the class E3/M1 (100 CO and 1000 mechanical operations) according to IEC 62271-102.
