3RA2435-8XE32-1NB3 SIEMENS

The 3RA2435-8XE32-1NB3 from Siemens is a complete contactor assembly specifically designed for star-delta (wye-delta) starting applications. This assembly facilitates a smooth and reduced-voltage start for three-phase motors, minimizing stress on the electrical grid and the motor itself. It is equipped with I/O-Link communication capabilities, enabling seamless integration into automated industrial environments for enhanced monitoring and control. The contactor assembly is rated for AC-3 duty, with a power rating of 37 kW at 400 V, making it suitable for medium to heavy-duty motor control applications. It operates on a 20-33 V AC/DC control voltage, providing flexibility in power supply options. The main contacts are arranged in a 3-pole configuration, ensuring reliable switching of the three-phase power supply. This device is size S2 and features screw terminals for secure and easy wiring. Electrical and mechanical interlocks are integrated to prevent short circuits and ensure safe operation. Furthermore, it includes 3 normally open (NO) and 3 normally closed (NC) auxiliary contacts, offering additional flexibility for control and signaling circuits.
