Siemens Sirius 3RF2 Solid-State Contactor

Solid-state contactor 1-phase 3RF2 AC 51 / 20 A / 40°C 48-460 V / 24 V DC low-noise semiconductor contactor SIRIUS 3RF23 for switching resistive/inductive loads, such as heaters or valves in a bottling plant. The units are wear-free and quiet, making them ideal for noise-sensitive areas (offices, hospitals). They are also extremely reliable at high switching frequencies. As the heatsink is already integrated, they can be used directly in the control cabinet. The compact design saves space on the DIN rail. Solid-state contactors can also be expanded to a wide range of applications by simply clicking on the standardized 3RF29 function modules. The units are approved for worldwide use (e.g., IEC and UL/CSA). The solid-state contactors are available as single-phase or three-phase units. They come in various rated power and rated operating voltages. They are designed for AC or DC operation and are available with screw, spring, or ring terminal connections. In addition to the 3RF29 function modules, control plugs and terminal covers are available as accessories. Simple, efficient, and always up-to-date - SIRIUS modular system.
