Siemens 3RF2310-1AA12 solid state contactor AC51 10.5A 40 degrees C

Semiconductor contactor 1-phase 3RF2 AC 51 / 10.5 A / 40 C 24-230 V / DC/AC 24 V screw connection Solid state contactor SIRIUS 3RF23 for switching resistive/inductive loads, e.g. radiators or valves in a bottling plant. The devices switch wear-free and silently and are therefore ideal for noise-sensitive areas (offices, hospitals). They are extremely reliable even at high switching frequencies. Since the heat sink is already integrated, they can be used directly in the control cabinet. The compact design saves space on the DIN rail. The semiconductor contactors can also be expanded for a wide range of applications with the standardized 3RF29 function modules by simply clicking them on. The devices are approved worldwide (e.g. IEC and UL/CSA). The semiconductor contactors are available as 1-phase or 3-phase devices. They are available for various power ratings and rated operating voltages. Designed for AC or DC operation, they are available with screw, spring-loaded or ring cable lug connections. In addition to the 3RF29 function modules, control plugs and terminal covers are also available as accessories. Simple, efficient, always up-to-date - the SIRIUS modular system.
