Railway relay, AC-3e/AC-3, 17 A, 7.5 kW / 400 V, 3-pole, DC 110 V, 0.7-1.25 US, electronic drive, with integrated varistor, auxiliary contacts: 1 NO + 1 NC, spring terminal connection, size: S0. The SIRIUS 3RT2 power relay is designed for switching motors under extreme conditions, such as in 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 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 working 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 terminal technology, the devices are also fully available with spring terminal connections for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are uniform across all sizes. The available connection blocks, functional modules, and the SIRIUS 3RV29 power supply system significantly reduce wiring effort. Simple, efficient, always up to date - the SIRIUS modular system.
