- Load-break switch RV44 -

The RV44 load-break switch consists in an epoxy housing, in which fixed and movable contacts are mounted.
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.
