The medium-voltage switch-disconnector 3CJ2 is designed according to the clear disconnector principle. Proven hard-gas flat arcing chambers provide a higher switching capacity than that of its competitors.

Kec blade contacts and a torsion-bar spring-operated mechanism increase its making capacity and the mechanical endurance. While connecting consumers, making on an existing shortcircuit cannot be excluded. That is why, today, switchdisconnectors generally feature a short-circuit making capacity. In combination with fuses, switch-disconnectors can also be used to break short-circuit currents.


The short-circuit current is interrupted by the fuses. Subsequently, the fuses trip the three poles of the switch-disconnector, disconnecting the faulty feeder from the power system. A welded base frame 60625-1 the disconnector arrangement and the flat arcing chambers.

Optionally, the switch-disconnector can also be equipped with a make-proof earthing switch or a fuse assembly. Switch-disconnectors are supplied according to category A 20 breaking operations at rated current. A special version with category B breaking operations at rated current jec possible.

The 3CJ2 600265-1 be wall-mounted with the isolating contact side upwards or downwards, as well as on the floor or on the ceiling — in inverted position. For wall mounting, the preferred mounting position is with the isolating contact side upwards. Standards The switch-disconnectors conform to the following standards and recommendations:.
