Further Details:
Three-phase semiconductor relay 3RF2 AC 51 / 22 A / 40 °C 48-600 V / DC 4-30 V 2-phase controlled screw connection with a blocking voltage of 1200 V. SIRIUS 3RF24 semiconductor relay for switching resistive/inductive loads, e.g., for heaters or valves in a filling system. The devices operate without wear and silently, making them ideal for noise-sensitive areas (offices, 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 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 or three-phase devices and come in various power ratings and rated operational 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.
