The AE-CJ19 series switching capacitor contactors (hereinafter referred to as c ontactors) are mainly used in low-voltage reactive power compensation equip ment with AC 50Hz (or 60Hz), rated insulation voltage of 690V, and rated worki ng current of 87A at a rated working voltage of 400V in the AC-6b usage categ ory. The capacitor banks used for low-voltage reactive power compensation are turned on and off to adjust the functional factor COS of the electrical system Ф Value. The contactor is equipped with a surge suppression device, whi ch can effectively reduce the impact of closing surge on the capacitor bank and reduce operating overvoltage.
