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.
