Disconnect switch with independent actuating mechanism, 3-pole handle on the drive transmission axis RA 630 P3/R 690V 630A Ui:1000V 63-811593-061.

The disconnect switches of the R series consist of the following main units:

• lower body equipped with current paths (fixed contacts and terminals),
• upper part equipped with fixed bridge contacts (RA) or fixed contacts with jaws (RAB),
• crossbars with movable contacts and internal combustion motors.

The independent actuating switches of the R series are designed for the distribution of electrical energy, the connection, and the protection of electrical devices from the effects of short circuits and overloads in three-phase networks.

They can be used as:

• main and outgoing switches in distribution devices,
• isolation switches,
• switches for control and protection of electric motors and other alternating current devices.
