Power contactor, AC-3 95 A, 45 kW / 400 V 2 NO + 2 NC, AC/DC 20-33 V 3-pole, 3NO, size S3 screw connection varistor integrated power contactor SIRIUS 3RT2 for switching motors. , The 3RT2 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. Many of the device combinations are factory-tested. The contactors offer the optimal connection to the controller for every application (parallel, via ASi or IO-Link). Integrated auxiliary switches reduce the complexity of your setup. The front connections enable easy wiring. The 3RT2 contactors are climate-proof, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready. , They are available in various sizes and in a wide power range in AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free and vibration-proof connection. , The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, etc., is standard for all sizes. The available connection modules, function modules and the SIRIUS 3RV29 feed-in system significantly reduce the wiring effort. , The 3RT2 power contactors replace the proven 3RT1 series (up to 55 kW). , Simple, efficient, always up-to-date - the SIRIUS modular system.
