The Siemens 3RT2017-1FB41 is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors up to 5.5 kW at 400 V AC. It features mirror contact elements, screw terminal connections, and a 24 V DC control coil with integrated diode, making it suitable for motor control centers (MCCs), automation systems, HVAC applications, and industrial power distribution systems.
This model belongs to the compact S00 frame size and is rated for AC-3 / AC-3e duty up to 12 A, making it a standard industrial-grade solution for small motor control and switching applications.
According to Siemens technical listings, the 3RT2017-1FB41 includes 1 NO auxiliary contact, 24 V DC coil with integrated diode, screw terminals, and S00 size construction, ensuring compact installation and reliable performance in control panels.
The mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for PLC interlocking, safety circuits, and machine monitoring systems, allowing the controller to verify the true ON/OFF status of the contactor for safe operation and diagnostics.
With screw terminals, wiring remains secure, vibration-resistant, and suitable for long-term industrial use.
