Siemens power contactor, AC-3 25 A, 11 kW / 400 V 1 S + 1 Ö, AC 230 V, 50 Hz, 3-pole, size S0 screw connection power contactor SIRIUS 3RT2 for motor control. The 3RT2 contactors are part of the SIRIUS system modular concept with optimally coordinated products. They impress with high performance while maintaining a compact design and high contact reliability. They can be combined in various ways with other components in the consumer branch. Many of the device combinations are factory tested. The contactors provide optimal connectivity 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 contactors are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. They are available in various sizes and a wide power range with AC and DC actuation. In addition to screw connection technology, the devices are also available with spring-loaded 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, function modules, and the SIRIUS 3RV29 power supply system significantly reduce wiring efforts. The 3RT2 power contactors replace the proven series 3RT1 (up to 55 kW). Simple, efficient, always.
