The 3RA2434-8XF32-1NB3 from Siemens is a contactor assembly specifically designed for star-delta (wye-delta) starting applications. This assembly is suitable for AC-3 utilization categories with a power rating of 22/30 kW at 400 V. It features an AC/DC operational voltage range of 20-33 V, providing flexibility in control circuit design. The contactor assembly includes a 3-pole configuration, ensuring reliable switching of three-phase circuits. It is a Size S2 contactor, indicating its physical dimensions and current handling capacity within the Siemens range. The assembly utilizes screw terminals for secure and easy electrical connections. Electrical and mechanical interlocks are incorporated to prevent simultaneous operation of certain contactors, enhancing safety and preventing short circuits. Furthermore, it comes with 3 normally open (NO) and 3 normally closed (NC) auxiliary contacts integrated into the design, offering additional control and feedback capabilities. This comprehensive design makes it suitable for motor starting applications where reduced inrush current is required.
