Siemens 3RF3410-1BB04 Contactor

Siemens 3RF3410-1BB04 is a solid-state, three-phase contactor from the SIRIUS 3RF34 family, designed to switch motors and other inductive loads with a DC-controlled input and a compact screw-terminal interface suitable for inside control panels. It uses a 24 V DC control coil and is 2-phase controlled, enabling instantaneous switching of the load via screw terminals without moving mechanical contacts. The device is rated for AC 53 duty with a load current of 9.2 A and supports load voltages from 48 to 480 VAC, specified for ambient temperatures up to 40 °C. The enclosure carries IP20 protection, and wiring is accomplished through robust screw-terminal connections built for industrial environments. This model is part of Siemens' SIRIUS solid-state switching lineup, commonly deployed in automation cabinets, conveyors, pumps, and fans, where compact, reliable motor control and fast switching are essential.
