The 3RT2 contactors are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4 ready. 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 standard for all sizes. The available connection modules, function modules and the SIRIUS 3RV29 feed-in system reduce the wiring effort considerably. The 3RT2 power contactors replace the proven 3RT1 series (up to 55 kW).
