SIEMENS AC Semiconductor Motor Starter

SIEMENS Soft start

Description
3TF Series AC Contactors are latest products of Siemens AG in 1990’s. The series products are suitable for frequency of 50/60Hz, rated insulation voltage up to 690 ~ 1000V, rated operational current up to 9A ~ 400A at rated operational voltage up to 380V under the utilization category AC - 3. 3TF Series AC Contactors are mainly used for making/breaking electric circuits at a long distance and for frequent starting stopping and reversing control of AC motors.They comply with IEC947, VDE0660, GB14048.

Features
• For better safety, conductive part are enclosed.
• Small sizes, light weight, material of arc chute adopts unsaturated resin, with good arc resistance, never splitting.
• The arc chute is enclosed , arc-over distance is small, with a compact electric cabinet.
• Construction of main contacts system is unique, abrasion of the contacts is small, with a long electric endurance.
• The operation of the magnet has many advantages such as good reliability, little consumption, low noise and high mechanical strength.
• The contactors have higher operation frequency and control capacity.
• Auxiliary contact block may be attached to 3TF30 ~ 50 Series AC Contactors.
• SIGUT - Siemens patent terminal, ensures easy and reliable connection, strog shock resistance and perfect safety protection.
