Siemens Dig.Industr. Coupling Relay 3RT2045-1KB40: additional details
Power relay, AC-3e/AC-3, 80 A, 37 kW / 400 V, 3-pole, DC 24 V, 0.8-1.2* US, with integrated varistor, auxiliary contacts: 1 NC + 1 NO, screw connection, size: S3, suitable for PLC outputs. The SIRIUS 3RT2 coupling relay is designed for switching motors and auxiliary and control circuits, specifically designed for direct connection to electronic controls. 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 consumer branch. Many of the device combinations are factory tested. Integrated auxiliary switches reduce the complexity of your setup. The front connections allow for easy wiring. The 3RT2 relays are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. In addition to screw connection technology, the devices are also available with spring-loaded terminals for quick, maintenance-free, and vibration-resistant connections. Simple, efficient, always up-to-date - the SIRIUS modular system.
