Contactor for connecting capacitors SLK_3SC19-25

The 3SC19 low voltage contactors are intended for connecting three-phase capacitive circuits (capacitors) in three-phase low voltage 400V networks. they are in 230V AC coils. Thanks to the use of modern technical solutions, the effects of transients (overvoltages, overcurrents) accompanying the switching on and off of capacitive receivers are reduced to a minimum. When a single capacitor is connected with a conventional contactor, the switching current may appear 30 times higher than the rated current of the capacitor. In the case of a battery with several elements, this current may reach a value several hundred times greater than the rated value. Such high values may lead to welding contacts of standard contactors and damage to the capacitor. The design of the contactor with
