Reversing contactors

 DOLD solid-state reversing contactors are used where it is required to change the direction of rotation of three-phase motors, to start them softly and/or to monitor their load. Diverse diagnosis functions help to be kept always informed on the operational condition of the motor. Our devices save space, wiring expenses and cost. 

Depending on model DOLD reversing contactors have either a reversing function (BH 9253 ) or a combination of reversing and current monitoring (BH 9255 ), or as in our new product (BI 9254 ) even a combination of reversing, softstart and active-power monitoring - all within a single device. There is a range of reversing contactors for motor power ratings up to 5.5 kW at three-phase 400 V available.
