Pre-installed auxiliary switches reduce the complexity of your design. The 3RT1 contactors are climate-resistant, approved for worldwide use (e.g. IEC and UL/CSA) and are IE3/IE4-ready.

They are available in various sizes and in a wide performance range. They can be operated with AC or DC, and some versions have a wide voltage range and a PLC control input. The devices can be connected in the main circuit by means of rails or box terminals. For the auxiliary and control circuit they are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection.

A wide range of accessories is available for these contactors, such as wiring kits that considerably reduce wiring outlay, auxiliary switches or terminal covers.
