Power contactor, AC-3e/AC-3, 51 A, 22 kW / 400 V, 3-pole, AC 110 V, 50 Hz / 120 V, 60 Hz, auxiliary contacts: 1 normally open + 1 normally closed, screw connection, size: S2. SIRIUS 3RT2 power contactor 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 offer optimal connectivity to the control system for every application (parallel, via ASI or IO-Link). Integrated auxiliary contacts reduce the complexity of your setup. The front 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 power range for AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded terminals for quick, maintenance-free, and vibration-resistant connections. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are standardized across all sizes. The available connection blocks, functional 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.
