The Siemens 3RT2017-2XB410LA2 is a SIRIUS 3RT2 series 3-pole power contactor (extended application / traction-type variant) designed for reliable switching of three-phase motors up to 5.5 kW at 400 V AC. It features mirror contact elements, a solid-state compatible electronic operating mechanism, and a 24–34 V DC control coil, making it suitable for advanced industrial automation, traction systems, and high-reliability motor control applications.
This model belongs to the compact S00 frame size and is rated for AC-3 / AC-3e duty up to 12 A, ensuring stable operation for standard industrial motor loads while also supporting extended voltage tolerance and electronic coil control.
Based on Siemens technical datasheets, the 2XB41 variant includes an electronic drive system with integrated varistor and spring/push-in terminals, enabling improved surge protection and compatibility with PLC and electronic output systems.
The mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for safety interlocking, PLC monitoring, and machine diagnostics, ensuring the system can confirm the actual ON/OFF state of the contactor.
With screw or spring terminal variants depending on configuration family, installation remains secure and vibration-resistant for industrial environments.
