Tronic Capacitor Duty Contactor 12KVAR

Our review

This Tronic contactor is made for a specific job: switching capacitor banks in power factor correction, whether that is a single three-phase bank or several steps switched in sequence. Capacitor switching is hard on standard contactors because of the high starting currents involved, and this unit is designed to suppress those currents rather than let them wear down the contacts.
It suits electricians, panel builders and maintenance teams putting together or repairing a PFC panel, particularly where banks are switched regularly. Before buying, confirm the number of steps and the arrangement of your bank, and check that the contactor's duty rating matches the reactive power of the capacitors it will switch. Compare it with general-purpose contactors of similar frame size, which are usually cheaper but not intended for capacitor duty, and with other capacitor-duty units on rating and coil voltage. Only the 12KVAR figure is stated here, so verify the rest against your panel design.
