cj19-25-11-230v chint 230vac 17a 1no + 1nc contactor for power factor correction
CHINT CJ19-25-11-230V capacitor switching contactor with 230 V AC coil for reactive power compensation and power factor correction systems.
Why Choose the Chint CJ19-25-11-230V Power Factor Correction Contactor?
The Chint CJ19-25-11-230V 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, helping improve the reliability and efficiency of reactive power compensation systems.
Unlike standard contactors, the CJ19 series incorporates a pre-charge resistor circuit that helps reduce capacitor inrush current during energisation. This design helps protect capacitor banks, minimise contact wear and extend the service life of electrical compensation equipment. The series is manufactured to IEC/EN 60947-4-1 standards.
With a rated operational current of 17 A, a 230 V AC coil supply and a three-pole configuration with 1 normally open and 1 normally closed auxiliary contact, the Chint CJ19-25-11-230V is suitable for automatic capacitor banks, power factor correction panels and industrial low-voltage distribution systems.
