🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, DC Coil – 3RT2018-1XF410LA2

🔹 Product Description

The Siemens 3RT2018-1XF410LA2 is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors up to 7.5 kW at 400 V AC. It features mirror contact elements, screw terminal connections, and an electronic DC control drive (72–125 V DC range), making it suitable for advanced motor control applications, industrial automation systems, and traction-type switching duties.

This model belongs to the compact S00 frame size and is rated for AC-3 / AC-3e duty up to 16 A, ensuring stable performance in medium-duty motor switching with enhanced control electronics.

According to Siemens technical datasheets for the 3RT2018 XF family, this variant uses an electronic operating mechanism with integrated protection (such as varistor), designed for a wide DC control voltage range (approx. 72–125 V DC), enabling flexible integration in modern PLC-driven systems.

The mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for PLC interlocking, safety circuits, and machine status monitoring, ensuring the controller can verify the actual switching state of the contactor for safe operation.

With screw terminals, installation remains secure, vibration-resistant, and suitable for continuous industrial use.
