3RA2423-8XF32-1BB4 SIEMENS

The 3RA2423-8XF32-1BB4 Siemens contactor assembly is specifically designed for star-delta (wye-delta) starting applications, commonly used to reduce inrush current during motor startup. This assembly is rated for AC-3 utilization, with a power rating of 11 kW at 400 V, making it suitable for medium-sized motor control applications. It operates on a 24 V DC control voltage, ensuring reliable and safe operation. The contactor is a 3-pole device, providing complete switching of all three phases of the motor. It is a Size S0 contactor, indicating its compact dimensions and suitability for space-constrained installations. The assembly features screw terminals for secure and easy electrical connections. An electrical and mechanical interlock is included, preventing simultaneous closure of the star and delta contactors, ensuring safe operation and preventing short circuits. It also has 3 normally open (NO) and 3 normally closed (NC) auxiliary contacts integrated, providing additional flexibility for control and monitoring circuits. This comprehensive design ensures efficient motor starting and reliable performance in industrial applications.
