The 3-phase semiconductor relay 3RF2 AC 51 / 50 A / 40 °C 48-600 V / DC 4-30 V is 3-phase controlled with screw connection and a blocking voltage of 1200 V. It is used for switching resistive and inductive loads, such as heaters or valves in a filling plant. The devices switch wear-free and silently, making them ideal for noise-sensitive areas like offices and hospitals. They are also extremely reliable at high switching frequencies. With the heat sink already integrated, they can be directly installed in the control cabinet. The compact design saves space on the DIN rail.

Additionally, the semiconductor relays can be easily expanded for various applications using the standardized functional modules 3RF29 by simple snap-on. The devices are globally approved, for example, according to IEC and UL/CSA. The semiconductor relays are available as single-phase or three-phase devices and come in various power ratings and rated operating voltages. They are designed for AC or DC actuation and are available with screw, spring-loaded, or ring terminal connections.

Accessories include not only the functional modules 3RF29 but also control plugs and terminal covers. Simple, efficient, always up-to-date - the SIRIUS system modular kit.
