Siemens Magnetic Contactor (3TF) 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, and are mainly used for making/breaking electric circuits at a long distance and for frequent starting/ stopping and reversing control of AC motors.
Key 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.
