APPLICATION
CJX1(3TF)Series AC Contactors are latest products in 1990’s.The series products are suitable for frequency of 50/60Hz,rated insulation voltage up to 690-1000V,rated opreational current up to 9A-400Aat raetd operational voltage up to 380V under the utilization category AC-3.3TF Sersies AC Contactors are mainly used for making breaking electric circuits at a ling distance and for frequent starting stopping and reversing control of AC motors ,They comply with IEC947,VDE0660MGB14048.
1.The altitude of the site of installation does not exceed 2000 meters baove sea levels;
2.The ambient air temperature:-25-+55℃;
3.Relative humidity does not exceed 50% at +40℃ and 90% at +25℃;
4.Atmospheric conditions:the air does not contain any explosive medium,corrosive gases and conductive dust;
5.Never be shocked and vibrate obviously;
6.Never be wetted by rain and snow.
FEATURES
1.For better safety,conductive part are enclosed.
2.Small sizes,light weight,material of arc chute adopts unsaturated resin,with good aec resistance,never splitting.
3.The aec chute is enclosed,arc-over distance is smallk,with a compact electric cabinet.
4.Construction of main contacts system is unique,abrasion of the contacts is small,with a long electric endurance.
5.The operation of the magnet has many bavantages suvh sa good reliability,little consumption,low noise and high mechanical strength.
6.The contactors hace higher operation frequency and control capacity.
7.Auxiliary contact block may be attached to CJX1-F(3TF30-50) series AC contactors.
8.SIGUT-Siemens patent terminal,ensures easy and reliable connection,strog shock resis tance and perfect safety protection.
