Power contactor, AC-3 50 A, 22 kW / 400 V 4 S, AC 230 V, 50 Hz 4-pole, size S2 screw connection 1 S + 1 Oe integrated SIRIUS 3RT23 contactor for switching resistive loads. The 3RT23 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 setup. The front connections enable easy wiring. The 3RT23 contactors are climate-resistant and approved worldwide (eg IEC and UL/CSA). 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. Simple, efficient, always up-to-date - the SIRIUS modular system.
