The 3TF6 vacuum contactors impress with their maximum performance combined with a compact design and high contact reliability. They are also characterized by a particularly long switching life. They are therefore particularly suitable for frequent switching in inching mode. Pre-assembled auxiliary switches reduce the complexity of your setup. The devices are approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready. They are available in two sizes, in AC or DC operation and in a wide power range. In the main circuit, the devices can be connected via rails. There are a wide range of accessories for these contactors, such as surge suppressors, auxiliary switches or terminal covers.
