3RT26 capacitor contactors are the new special contactors for switching capacitive loads. They are based on the field-proven 3RT2 basic units and have precharging resistors that are decoupled again following attenuation of the switch-on peak current. 3RT26 capacitor contactors have a significantly higher service life than the predecessor type, with a simultaneous increase in performance. With the addition of performance classes in the intermediate sizes, the portfolio offers just the right contactor for your application. The 3RT26 series offers devices that switch up to 33 kvar with a width of just 45 mm, and up to 75 kvar on the basis of the 65 mm wide basic units. 3RT26 capacitor contactors are frequently used for switching power contactors in reactive power compensation systems, and they are suitable here for solutions with and without reactors. Capacitor contactors are recommended on the primary side even in the case of converters without precharging resistors and an unknown peak current value. For these and other applications, the options with integrated, unassigned auxiliary switches have been perceptibly expanded. 3RT26 capacitor contactors now offer a variant with two NC contacts (2NC) in all performance classes.
