Vacuum contactor 3TF6 for switching motors. The 3TF6 vacuum contactors impress with high performance while maintaining a compact design and high contact reliability. They also feature an exceptionally long switching lifespan, making them particularly suitable for frequent switching in momentary operation. Pre-assembled auxiliary switches reduce the complexity of your setup. The devices are globally approved (e.g., IEC and UL/CSA) and are IE3/IE4 ready. They are available in two sizes, with AC or DC actuation, and across a wide power range. In the main circuit, the devices can be connected via rails. A variety of accessories is available for these contactors, such as surge protectors, auxiliary switches, or terminal covers.
