The 3RT24 contactors are part of the SIRIUS system modules with their optimally coordinated products. They convince by high power with a compact design and high contact reliability. They can be combined in a variety of ways with other components in the load feeder. Many of the device combinations have been tested at the factory. The contactors provide optimum connection to the controller (parallel, via ASi or IO-Link) for each application. Integrated auxiliary switches reduce the complexity of your setup. The front connections allow simple wiring. The 3RT24 contactors are climate-proof and worldwide approved (e.g. IEC AND UL/CSA).
They are available in various sizes and in a wide power range in AC and DC operation with screw connection technology.
The comprehensive accessories for example Auxiliary switch, auxiliary release, etc. is uniform for all sizes.
