Railway contactor, AC-3 32 A, 15 kW / 400 V 1 NO + 1 NC with electronic drive DC 72 V, 0.7-1.25*US with integrated varistor 3-pole, size S0 spring-loaded connection 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 many 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 structure. The front connections enable easy wiring. The 3RT2 contactors are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4 ready. 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 reduce the wiring effort considerably.Simple, efficient, always up-to-date - the SIRIUS modular system.
