Power contactor, AC-3e/AC-3, 51 A, 22 kW / 400 V, 3-pole, AC 230 V, 50 Hz, auxiliary contacts: 1 NO + 1 NC, main circuit: screw connection, control and auxiliary circuit: spring-loaded connection, size: S2. The SIRIUS 3RT2 power contactor is designed for motor switching. The 3RT2 contactors are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance while maintaining a compact design and high contact reliability. They can be combined in various ways with other components in the load branch. Many of the device combinations are factory-tested. The contactors provide optimal connectivity to the control system for every application (parallel, via ASI or IO-Link). Integrated auxiliary switches reduce the complexity of your setup. The front-side connections allow for easy wiring. The 3RT2 contactors are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. They are available in various sizes and a wide range of power ratings for AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded connections for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary switches, auxiliary relays, etc., are standardized for all sizes. The available connection blocks, function modules, and the SIRIUS 3RV29 power supply system significantly reduce 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.
