The 3RT2 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. Many of the device combinations have been factory tested. The contactors offer the best connection to the automation level for every application (parallel, via ASi or IO-Link): Integrated auxiliary switches reduce the complexity of your design. The front-panel terminals simplify the wiring. The 3RT2 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 with AC and DC operation. In addition to screw terminals, all the devices are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases etc. is standardized for all sizes. The available link modules, function modules and the SIRIUS 3RV29 infeed system considerably reduce the wiring expense. The 3RT2 power contactors replace the well-proven 3RT1 series (up to 55 kW).
