Product Description
1.Product overview:
JCZ8-24KV series AC high voltage vacuum contactor is suitable for AC 50~60Hz,main circuit rated voltage 24KV,rated current from 160A to 630A power network system for remote making and breaking and frequent starting and controlling AC motors, transformers and capacitor banks. It is especially suitable for switching loads of bulk capacitor banks.
2.Product features:
1)This series of contactor is composed of the insulating frame,driving crank arm,the electromagnetic system,the auxiliary switch,the vacuum switch tube and other components.
2)The structure of high voltage circuit and low voltage control upper and lower split structure,with layout beautiful,safe and reliable,easy to install and maintain.
3)This series of vacuum contactor has a large stroke, strong breaking capacity, small closing and opening bounce, and stable performance. The three-phase performance is good, especially suitable for switching the load of the capacitor bank.3.The use of the environment conditions
3.1.Ambient temperature:-25 ºC ~ +40 ºC.
3.2.Installation site altitude does not exceed 2000m.
3.3.The relative humidity of the air,the wettest month average monthly maximum relative humidity of 90%,monthly average minimum temperature of 25ºC,and taking into account the cream of temperature changes on the surface of the product.
3.4.Environment:anhydrous invasion,non-corrosive and flammable gas and excessive vibration occasions.
4.Product Specification
Rated voltage:24kV, rated current:160A,250A ,400A ,630A,800A.
5. Maintenance
5.1.We recommend the user establish a regular maintenance system to ensure that 24kv vacuum contactor is in good condition.Periodically clean the insulation frame,the vacuum switch tube and circuit system to ensure work insulation and normal operation.
