Power relay, AC-3e/AC-3, 9 A, 4 kW / 400 V, 3-pole, AC 230 V, 50 Hz, auxiliary contacts: 2 NC + 2 NO, screw connection, size: S0, removable auxiliary switch. SIRIUS 3RT2 power relay for motor switching. The 3RT2 relays 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 relays provide optimal connectivity for every application (parallel, via ASI or IO-Link). Integrated auxiliary switches reduce the complexity of your setup. The front connections allow for easy wiring. The 3RT2 relays are climate-resistant, globally certified (e.g., IEC and UL/CSA), and IE3/IE4 ready. They are available in various sizes and a wide range of power ratings in AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded terminals for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary switches, auxiliary relays, etc., are uniform across all sizes. The available connection modules, function modules, and the SIRIUS 3RV29 feed-in system significantly reduce wiring effort. The 3RT2 power relays replace the proven 3RT1 series (up to 55 kW). Simple, efficient, always up to date - the SIRIUS modular system.
