🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, AC Coil – 3RT2016-1AF018K

🔹 Product Description

The Siemens 3RT2016-1AF018K is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors and industrial loads. It features mirror contact elements, screw terminal connections, and a 110 V AC control coil, making it suitable for use in motor control centers (MCCs), automation systems, HVAC installations, machinery, and industrial power distribution systems.

This model belongs to the compact S00 frame size and is rated for AC-3 duty up to 9 A, with a motor capacity of approximately 4 kW at 400 V AC, depending on application conditions. It is commonly used for small to medium motor control applications in industrial environments where reliability and compact installation are important.

The integrated mirror contact elements provide mechanically linked feedback of the main contact position, which is essential for PLC interlocking, safety circuits, and monitoring systems. This ensures that the control system can verify whether the contactor is truly ON or OFF, improving operational safety and diagnostics in automation systems.

With robust screw terminals, the 3RT2016-1AF018K ensures secure wiring, vibration resistance, and easy installation inside control panels, making it suitable for long-term industrial operation.
