cj19-43-11-110v chint 110vac 29a 1no + 1nc contactor for power factor correction
CHINT CJ19-43-11-110V capacitor switching contactor with 110 V AC coil for reactive power compensation and power factor correction systems.
Why Choose the Chint CJ19-43-11-110V Power Factor Correction Contactor?
The Chint CJ19-43-11-110V 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 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 service 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 110 V AC coil supply and a three-pole configuration with 1 normally open and 1 normally closed auxiliary contact, the Chint CJ19-43-11-110V is suitable for automatic capacitor banks, power factor correction panels and industrial low-voltage distribution systems.
