Railway contactor, AC-3 16 A, 7.5 kW / 400 V 1 NC, DC 24-34 V, 0.7-1.25*US with integrated varistor size S00, spring-loaded connection suitable for PLC outputs hanging installation position Contactor SIRIUS 3RT2 for switching motors under extreme conditions, e.g. for railway applications. , The 3RT2 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress with their high performance combined with a compact design and high contact reliability. They can be combined in a variety of ways with other components in the load feeder. Many of the device combinations are factory-tested. The contactors offer the optimal connection to the controller for every application (parallel, via ASi or IO-Link). Integrated auxiliary switches reduce the complexity of your setup. The front connections enable easy wiring. The 3RT2 contactors are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready. This variant is characterized by an extended operating and temperature range for harsher environmental conditions. , They are available in various sizes and in a wide power range in AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free and vibration-proof connection. , The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, etc., is standardized for all sizes. The available connection modules, function modules and the SIRIUS 3RV29 feed-in system significantly reduce the wiring effort. , Simple, efficient, always up-to-date - the SIRIUS modular system.
