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,VDE0660, MGB14048.
1)The altitude of the site of installation does not exceed 2000 meters above sea levels.
2)The ambient air temperature: -25 ~ +55°C
3)Relative humidity does not exceed 50% at +40¼C and 90% at +25°C
4)tmospheric conditions: the air does not contain any explosive medium, corrosive gases and conductive dust.
5)Never be shocked and vibrated obviously.
6)Never be wetted by rain and snow.
1)For better safety, conductive part are enclosed.
2)Small sizes, light weight, material of arc chute adopts unsaturated resin, with good arc resistance,
3)The arc chute is enclosed , arc-over distance is small, 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 advantages such as good reliability, little consumption,
low noise and high mechanical strength.
6)The contactors have higher operation frequency and control capacity.
7)Auxiliary contact block may be attached to 3TF30 ~ 50 Series AC Contactors.
8)SIGUT - Siemens patent terminal, ensures easy and reliable connection, strog shock resistance and
