3RA2423-8XH32-2BB4 SIEMENS

The 3RA2423-8XH32-2BB4 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 equipped with an AS-i (Actuator Sensor Interface) communication interface, facilitating seamless integration into automated systems. It is rated for AC-3 duty, making it suitable for switching AC induction motors with a power rating of 11 kW at 400 V. The control voltage is 24 V DC, ensuring compatibility with standard industrial control circuits. This 3-pole contactor assembly is size S0, indicating its compact dimensions and suitability for space-constrained installations. It features spring-type terminals for quick and reliable wiring connections, reducing installation time and effort. An electrical and mechanical interlock is incorporated to prevent simultaneous closure of the main and delta contactors, ensuring safe operation. The assembly includes 3 normally open (NO) and 3 normally closed (NC) auxiliary contacts, providing additional flexibility for control and monitoring functions. This integrated design simplifies wiring and reduces the overall footprint of the motor starter.
