Solid-state relay 3RF2170-1AA02: further details Solid-state relay, 1-phase 3RF2 Width 22.5 mm, 70 A 24-230 V / DC 24 V Screw connection SIRIUS 3RF21 solid-state relay for switching resistive/inductive loads, e.g. radiators or valves. 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. 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 standardised 3RF29 function modules. The units are approved worldwide (e.g. IEC and UL/CSA).The solid-state relays are available as 1-phase units in two widths or as 3-phase units. They are available for different power ratings and rated operating voltages. Designed for AC or DC actuation, they are available with screw, spring-cage or ring terminal 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. , EAN: 4011209573932.
