Interlock switch with independent operation, 3-pole handle on the axis RA400 P3/R 690V 400A Ui:1000V.

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

• Lower body equipped with current paths (fixed contacts and terminals).
• Upper body equipped with bridge fixed contacts (RA) or fixed contacts with jaws (RAB).
• Bridges with movable and heated contacts.
• Independent (snap) actuator unit.

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

They can be used as:

• Main switches and outgoing switches in distribution devices.
• Isolation switches.
• Switches for controlling and protecting electric motors and other AC devices.
