Load-break switch
12 - 24 kV, 630 - 1 250 A | RV44
DEBA
The switch is filled with SF6 gas (sulphur hexafluoride) and is sealed for life. The special characteristics of the SF6 gas guarantee a perfectly insulating and arc-extinguishing function within the housing.
As a result of the ideal switching speed at the switch/drive-mechanism combination, the load-break switch features very short arc times. The patented switching principle combines maximum gas revolving effect with a precise finishing of the electrical contacts. This guarantees excellent dielectrical features and a minimum of contact erosion.
The load-break switch is a two-position switch that connects or interrupts the voltage between the high voltage cables and the bus bar. The position of the load-break switch is clearly indicated in the single line diagram.
Depending on the version, the load-break switch is operated manually or electrically. See "Drive mechanism" Manual operation is done with the operating handle supplied.
