Railway relay, AC-3 40 A, 18.5 kW / 400 V 2 S + 2 Ö DC 72 V, 0.7-1.25 US, with varistor, 3-pole, size S2, spring-loaded connection. SIRIUS 3RT2 relay for switching motors under extreme conditions, e.g., for railway applications. The 3RT2 relays are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance in 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 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 relays are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. This variant features an extended operating and temperature range for harsher environmental conditions. They are available in various sizes and in a wide power range for AC and DC operation. In addition to screw connection technology, the devices are also fully available with spring-loaded connections for quick, maintenance-free, and vibration-resistant connections. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are uniform across all sizes. The available connection blocks, function modules, and the SIRIUS 3RV29 power supply system significantly reduce wiring effort. Simple, efficient, always up-to-date - the SIRIUS modular system.
