cj19-95-21-240v chint 230vac 63a 2no + 1nc contactor for power factor correction
CHINT CJ19-95-21-240V capacitor switching contactor with 240 V AC coil for reactive power compensation and power factor correction systems.
Why Choose the Chint CJ19-95-21-240V Power Factor Correction Contactor?
The Chint CJ19-95-21-240V is a high-capacity 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 specifically engineered for AC-6b capacitor switching applications, providing dependable reactive power compensation and improved electrical system efficiency.
Unlike standard contactors, the CJ19 series is designed specifically for capacitor switching duties and incorporates a pre-charge resistor circuit to reduce capacitor inrush current during energisation. This helps protect capacitor banks, minimise contact stress and extend the operational life of power factor correction equipment. The series is manufactured according to IEC/EN 60947-4-1 standards.
With a rated operational current of 72.2 A at 400 V AC, a 240 V AC coil supply and a three-pole configuration with 2 normally open and 1 normally closed auxiliary contacts, the Chint CJ19-95-21-240V is suitable for larger automatic capacitor banks, reactive power compensation panels and industrial low-voltage distribution systems.
