The Siemens solid-state contactor device are non-wearing and silent and are therefore ideal for noise-sensitive areas. They are also extremely reliable at high switching frequencies. As the heat sink is already integrated, they can be used directly in the control cabinet. The solid-state contactors can also be expanded for a wide range of applications by simply clicking on the standardized 3RF29 function modules. The devices are approved for worldwide use (e.g. IEC and UL/CSA).

In addition to the 3RF29 function modules, control connectors and terminal covers are also available as accessories.
