Power contactor SIRIUS 3RT1 for switching motors.

The 3RT1 contactors are part of the modular SIRIUS system with its optimally coordinated products. They offer convincing performance from a compact design with high contact reliability. They can be combined with a variety of other components in the load feeder. The contactors offer the best connection to the automation level for every application (direct or via PLC input). 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.
