Reversing contactors

Reversing contactors

POWERSWITCH - High functionality in the smallest space

DOLD reversing contactors of the POWERSWITCH series are used to change the direction of rotation in alternating current motors, start them gently and/or to monitor their load. Various diagnostic functions inform you constantly about the operating condition of the motor. The DOLD reversing contactors save space and have few wires as all functions are combined in a single housing. Costs can also be saved as an alternative to a frequency converter. The devices are universally usable, e.g. for extruders, pumps, actuators or conveyors.
