Siemens Sirius 3RF2 Solid-State Contactor

Solid-state contactor single-phase 3RF2 AC 51 / 50 A / 40°C 48-600 V / 24 V DC Ring cable connection semiconductor contactor SIRIUS 3RF23 for switching resistive/inductive loads, e.g., heaters or valves in bottling plant. Units are wear-free and silent, making them ideal for noise-sensitive areas (offices, hospitals). They are also extremely reliable at high switching frequencies. Since 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 for a wide range of applications by simply clicking on the standardized 3RF29 function modules. Units are approved for worldwide use (e.g., IEC and UL/CSA). Solid-state contactors are available as single-phase or three-phase units. They come in various rated power and operational voltage ratings. 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 also available as accessories. Simple, efficient, and always up-to-date - the SIRIUS modular system.
