Siemens Sirius 3RF3 Solid-State Contactor

Solid-state contactor 3-phase 3RF3 AC 53 / 3.8 A / 40°C 48-480 V / 110-230 V AC Reversing circuit Instant switching screw terminal semiconductor reversing contactor SIRIUS 3RF34 for switching motors for frequent reversing, e.g., in conveyor systems. Units are wear-free and silent, making them ideal for noise-sensitive areas (offices, hospitals). The reversing contactors have an integrated interlock. They are also extremely reliable at high switching frequencies. As the heat sink is already integrated, they can be used directly in the control panel. The compact design saves space on the DIN rail. Devices are approved for worldwide use (e.g., IEC and UL/CSA). Solid-state reversing contactors are available in two widths for different nominal power. They are designed for AC or DC operation and are equipped with screw terminals. Link modules, adapters, and labels are available as accessories. Simple, efficient, and always up-to-date - SIRIUS modular system.
