1-Phase Solid State Contactor 30A continuous current rating 48-600V AC main circuit 4-30V DC control circuit 1200V blocking voltage Screw terminals

The Siemens 3RF2330-1AA45 is a 1-phase solid-state contactor from the 3RF2 series. It is designed for AC 51 applications with a continuous current rating of 30A at 40Β°C. This model operates with a main circuit voltage range of 48-600V AC and a control circuit voltage of 4-30V DC. It features a blocking voltage of 1200V and utilizes screw terminals for connection.

This solid-state contactor is ideal for applications requiring frequent switching or where mechanical contactors are unsuitable due to high switching frequencies or extreme environmental conditions. Industries such as general manufacturing, HVAC, and machine building can benefit from its reliable, long-lasting performance. It is particularly useful for controlling resistive or inductive loads where precise switching and minimal wear are essential.
