Siemens Digital Industry Coupling Relay 3RT2045-3KB40: 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 normally closed + 1 normally open, varistor integrated, main circuit: screw connection, control and auxiliary circuit: spring-loaded connection, size: S3, suitable for PLC outputs. Coupling relay SIRIUS 3RT2 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 connection for a quick, maintenance-free, and vibration-resistant connection. Simple, efficient, always up to date - the SIRIUS modular system.
