Product Description

Product Description

Application

A9 ~ 300 AC contactor(hereafter refer to as contactor) is mainly used in power system with AC 50Hz(or 60Hz),therated working voltage up to 660V,under the applicaton category of AC-3,when the rated working voltage 380V,the rated operating current to 300A electrical,for the long-distance range making and breaking the electric circuit,and combines the electorm agnetism starter with the suitable thermal overload relay or the electronic protector to protect against the possible overload electric circuit during operation(running).

The first blank: The basic specification code is indicated with the rated working voltage;380V rated operating curent numerical value under AC-3 application category,

The second blank: The main contact pair indicated with two figures,ones place expressed NC contact Pair; The tens digit expressed NO contact pair.

The final blank: The auxiliary contact pair indicated with two figures,ones placeexpressed NC;The contact pair,the tens digit expressed NO contact pair.

Common Work Condition And Installing Condition

a.The installation site elevation does not surpass 2000m;
b.Ambient air temperature should not over +40℃,also not over +35℃ within 24h,the lower limit of ambient air temperature is -5℃;
c.The air relative humidity at installation site should not over 50% when the maximum temperature is +40℃;the higher relative humidity are allowed under lo- wer temperature,for example,90% at 20℃,It must take the mesures on the product occuring dew because of the change of temperature.

d.The installation site pollution class is 3 ;

e.The contactir can be mounted vertically or horizontally.If vertically mounts,the gradient between the mounted surface and the perpendicular plans is not bigger than ±30%; (See Fig 1)
