Semiconductor contactor 3-phase 3RF3 AC 53 / 5.2 A / 40 °C 48-600 V / 110-230 V AC 2-phase controlled instantaneous switching spring-loaded connection Semiconductor contactor SIRIUS 3RF34 for switching motors for frequent switching on and off, e.g. in conveyor technology. 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 top hat rail. The devices are approved worldwide (e.g. IEC and UL/CSA). The semiconductor contactors are available in two widths for different power ratings and rated operating voltages. They are designed for AC or DC operation and are available with screw or spring-loaded connections. Connection modules and adapters as well as identification plates are available as accessories. Simple, efficient, always up-to-date - the SIRIUS modular system.
