Siemens 3RF2410-1BD04 Solid State Contactor

Siemens 3RF2410-1BD04 is a three-phase solid-state contactor that switches 48–480 VAC loads from a 24 V DC control signal, delivering quiet, fast switching for motors and other inductive loads. This 3RF2 device uses screw terminals for straightforward wiring and includes a reversing circuit option for bidirectional motor control when paired with other control hardware. It is designed for inductive (AC53) loads and, in this family’s common configurations, carries a continuous current around 7.4 A with a 40 °C ambient limit, plus a blocking voltage up to 1200 V to tolerate voltage transients. The compact construction and Siemens engineering ensure reliable switching in control panels and motor-start assemblies, enabling solid-state performance with minimal mechanical wear compared to traditional relays.
