£104.64
The Chint CJ19-43-11-230V is a specialised power factor correction contactor designed for reliable switching and control of capacitor banks in industrial and commercial electrical systems. As part of the Chint CJ19 capacitor switching contactor series, it is engineered specifically for AC-6b capacitor switching applications, providing dependable reactive power compensation control and improved electrical system efficiency.
Unlike standard contactors, the CJ19 series incorporates capacitor switching technology with a pre-charge resistor circuit that helps suppress inrush current during capacitor energisation. This helps protect capacitor banks, reduce switching stress and extend the operational life of compensation equipment. The series is manufactured according to IEC/EN 60947-4-1 standards.
With a rated operational current of 29 A at 400 V AC, a 230 V AC coil supply and a three-pole configuration with 1 normally open and 1 normally closed auxiliary contact, the Chint CJ19-43-11-230V is suitable for automatic capacitor banks, power factor correction panels and industrial low-voltage distribution systems.
Power factor correction contactors such as the Chint CJ19-43-11-230V are designed to safely connect and disconnect capacitor banks used in reactive power compensation systems. Their dedicated capacitor switching design helps manage high charging currents and reduces electrical stress during switching operations.
By improving reactive power management, capacitor switching systems can help enhance power quality, reduce unnecessary energy losses and support stable operation of industrial electrical networks.
