🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, AC Coil – 3RT2017-1AP018K

🔹 Product Description

The Siemens 3RT2017-1AP018K 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, spring-loaded (push-in) terminals, and a 230 V AC control coil (50/60 Hz), making it suitable for use in 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 ideal for small motor control applications where fast wiring and modern maintenance-free connections are preferred.

The integrated mirror contact elements provide mechanically linked feedback of the main contacts. This is essential for PLC interlocking, safety circuits, and machine monitoring, ensuring the controller can verify the actual ON/OFF status of the contactor for safe operation and diagnostics.

With spring-loaded (push-in) terminals, installation becomes faster and more vibration-resistant compared to screw terminals, making it especially useful in high-vibration industrial panels and reducing wiring maintenance time.
