The Siemens 3RT2016-2XB410LA2 is a SIRIUS 3RT2 series 3-pole power contactor (traction / extended application variant) designed for reliable switching of three-phase motors up to 4 kW at 400 V AC. It features mirror contact elements, screw terminal connections, and a 24–34 V DC electronic coil with integrated varistor, making it suitable for demanding industrial automation, traction systems, and control applications.
This model belongs to the compact S00 frame size and is rated for AC-3 / AC-3e duty up to 9 A, ensuring dependable operation in small motor switching and control circuits.
It includes a spring-assisted / extended-range electronic coil drive, which allows stable operation across a wide control voltage range and improves immunity against voltage fluctuations. The integrated varistor suppression helps protect the control electronics from switching surges.
The mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for PLC interlocking, safety monitoring, and system diagnostics, ensuring the controller always receives a true ON/OFF status of the contactor.
With screw terminals, wiring remains secure, vibration-resistant, and suitable for industrial panel environments where reliability is critical.
