Further Details: Semiconductor relay, 3-phase 3RF2 55 A / 40 °C 48-600 V / DC 4-30 V, 3-phase controlled, screw connection, blocking voltage 1200 V. SIRIUS 3RF22 semiconductor relay for switching resistive/inductive loads, e.g., heaters or valves in a filling plant. The devices switch wear-free and silently, making them ideal for noise-sensitive areas (offices, 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 using the standardized function modules 3RF29 by simply snapping them on. The devices are globally approved (e.g., IEC and UL/CSA). The semiconductor relays are available as single-phase devices in two widths or as three-phase devices. They 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.
