Siemens halvlederrelé Sirius 3RF20, 45 mm bredde 3RF2050-1AA45 laststrøm 50 A koblingsspenning 48 - 600 V/AC (3RF2050-1AA45)

***phase-out type*** semiconductor relay, 1-phase 3RF2 width 45 mm, 50 A 48-600 V / 4-30 V DC screw terminal blocking voltage 1200 V for mounting on available cooling surfaces solid-state relay SIRIUS 3RF20 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. The compact design saves space on the cooling surface. The solid-state relays 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 relays are available as single-phase devices in two widths, or as 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.
