Contactor, AC-1, 275A/690 V/40 °C, S6, 3-pole, AC/DC 220-240V, with varistor, 2NO+2NC, connecting rail/spring-loaded connection Contactor SIRIUS 3RT14 for switching resistive loads. , The 3RT1 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress with high performance combined with a compact design and high contact reliability. They can be combined in a variety of ways with other components in the load feeder. The contactors offer the right connection to the controller for every application (directly or via PLC input). Pre-assembled auxiliary switches reduce the complexity of your setup. The 3RT1 contactors are climate-proof and approved worldwide (e.g. IEC and UL/CSA). , They are available in different sizes and in a wide power range. They can be operated with AC or DC, some variants have a wide voltage range and a PLC control input. In the main circuit, the devices can be connected via rails or box terminals. For the auxiliary and control circuits, they are also available with spring-loaded connections for a quick, maintenance-free and vibration-proof connection. There are a wide range of accessories for these contactors, such as wiring kits that significantly reduce the wiring effort, auxiliary switches or terminal covers. , Simple, efficient, always up-to-date - the SIRIUS modular system.
