Railway relay, AC-3e/AC-3, 65 A, 30 kW / 400 V, 3-pole, DC 24 V, 0.7-1.25 US, electronic drive, with integrated varistor, auxiliary contacts: 1 NO + 1 NC, screw connection, size: S2 power relay SIRIUS 3RT2 for switching motors under extreme conditions, e.g., for railway applications. The 3RT2 relays are part of the SIRIUS system modular concept 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 the optimal connection 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 a wide power range in AC and DC actuators. 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 contacts, auxiliary relays, etc., are standardized for 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 system modular concept.
