Siemens Sirius 3RF2 Solid-State Contactor

Solid-state contactor 1-phase 3RF2 AC 15 / 12 A / 40°C 48-600 V / 24 V DC Instant switching semiconductor contactor SIRIUS 3RF23 for switching resistive/inductive loads, e.g., of heaters or valves in a bottling plant. The devices are wear-free and quiet, ideal for noise-sensitive areas (offices, hospitals). Extremely reliable at high switching frequencies. As the heat sink is already integrated, they can be used directly in the switch cabinet. The compact design saves space on the DIN rail. Solid-state contactors can be extended 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). Solid-state contactors are available as single-phase or three-phase units. They come in various nominal power and operating voltage ratings. Designed for AC or DC operation and 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.
