3RA2417-8XH31-2BB4 SIEMENS

The 3RA2417-8XH31-2BB4 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 standard AC motor control applications with a power rating of 11 kW at 400 V. The control voltage is 24 V DC, ensuring compatibility with a wide range of control circuits. The contactor features a 3-pole configuration, providing reliable switching for three-phase power systems. Its size is S00, indicating a compact design suitable for space-constrained installations. Spring-type terminals enable quick and secure wiring connections, reducing installation time and improving reliability. Electrical and mechanical interlocks are incorporated to prevent simultaneous operation of contactors, enhancing safety and preventing short circuits. Furthermore, it includes 3 normally open (NO) auxiliary contacts, providing additional flexibility for control and monitoring functions.
