Siemens 3RF2320-1AA44 Protezione dei semiconduttori Commutazione zero crossing 1 NA 20 W 20 A Adatto per marchio (relè):

Solid-state contactor 1-phase 3RF2 AC 51 / 20 A / 40 °C 48-460 V / 4-30 V DC screw terminal solid-state contactor SIRIUS 3RF23 for switching resistive/inductive loads, e.g. of heaters or valves in a bottling plant.
The devices are non-wearing and silent and are therefore ideal for noise-sensitive areas (offices, hospitals). 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 compact design saves space on the mounting rail. 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).
The solid-state contactors are available as single-phase or three-phase devices. They are available for different power ratings and rated operating voltages. Designed for AC or DC operation, they are available with screw, spring-type or ring terminal lug connections.
In addition to the 3RF29 function modules, control connectors and terminal covers are also available as accessories.
Simple, efficient and always up to date - SIRIUS modular system.
