3RA2423-8XH32-1BB4 SIEMENS

The 3RA2423-8XH32-1BB4 Siemens contactor assembly is specifically designed for star-delta (wye-delta) starting applications, providing a reduced voltage start to minimize inrush current and mechanical stress on motors. This assembly is equipped with an AS-i (Actuator Sensor Interface) communication interface, enabling seamless integration into automated systems for efficient control and monitoring. It is rated for AC-3 duty, making it suitable for standard AC induction motor applications with a power rating of 11 kW at 400 V. The contactor coils operate on 24 V DC, ensuring compatibility with common control circuits and providing reliable operation. This 3-pole contactor assembly is size S0, offering a compact design for space-saving installation in control panels. Screw terminals facilitate secure and easy wiring connections, while the electrical and mechanical interlock mechanisms prevent simultaneous closure of the main and delta contactors, ensuring safe operation. The integrated auxiliary contacts, consisting of 3 normally open (NO) and 3 normally closed (NC) contacts, provide additional flexibility for control and monitoring functions. This comprehensive contactor assembly offers a robust and reliable solution for motor starting applications in various industrial settings.
