Contactor, 4 S, AC-1: 60 A railway DC 24 V, 0.7 ... 1.25* US, 4-pole, 4S, size S2, spring-loaded terminal 1 S + 1 NC integrated with varistor Contactor SIRIUS 3RT23 for switching resistive loads under extreme conditions, e.g. for railway applications. The 3RT23 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress with 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 3RT23 contactors are climate-proof and approved worldwide (e.g. IEC and UL/CSA). This variant is characterized by an extended working 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 a quick, maintenance-free and vibration-proof connection. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, etc., is standard for all sizes. Simple, efficient, always up-to-date - the SIRIUS modular system.
