3-phase semiconductor relay 3RF2 AC 51 / 20 A / 40 °C 48-600 V / 110 V AC 2-phase controlled. Screw connection. Blocking voltage 1200 V. SIRIUS semiconductor relay 3RF24 for switching resistive and 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 such as 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 with the standardized function modules 3RF29 by simply snapping them on. The devices are globally approved, e.g., according to IEC and UL/CSA. The semiconductor relays are available as single-phase or three-phase devices and come in various ratings and 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 kit. EAN: 4011209777460.
