Additional details:
Semiconductor relay, single-phase, 3RF2, width 45 mm, 50 A, 48-460 V / DC 4-30 V, screw connection. SIRIUS 3RF20 semiconductor relay 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. The compact design saves space on the cooling surface. Additionally, the semiconductor relays can be easily expanded for various applications by simply clicking on the standardized function modules 3RF29. The devices are globally certified, e.g., according to IEC and UL/CSA. The semiconductor relays are available as single-phase devices in two widths or as three-phase devices and are offered for various power ratings and rated operating voltages. Designed for AC or DC actuation, they are available with screw, spring-loaded, or ring terminal connections. Accessories include not only the function modules 3RF29 but also control plugs and terminal covers. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
