Tronic CT CJ19-125 Capacitor Duty Contactor, 60KVAR 400V/440V

Our review

The Tronic CT CJ19-125 is a capacitor duty contactor, a switching device made for circuits where capacitors are the load rather than ordinary motors or resistive equipment. Its rating of 60KVAR at 400V/440V places it in the category of contactors used with power factor correction banks, where the inrush current when a capacitor is energised is far harsher than on a standard contactor. That difference matters: a general purpose contactor of similar frame size is not the right substitute, because capacitor duty units are built to handle those current surges. This unit suits electricians, panel builders and maintenance teams working on capacitor banks in commercial or industrial installations. Before ordering, confirm the reactive power of your bank does not exceed the 60KVAR rating, check that your system voltage matches the 400V/440V figure, and verify the coil voltage your control circuit uses, since that detail is not stated here and must be confirmed with the seller. Also compare the number of poles and auxiliary contacts against your panel design. If your bank is larger, a higher rated contactor or a different switching method may be the better route.
