The Siemens 3RT2016-1AB018K is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors and industrial loads. It is equipped with mirror contact elements, screw terminal connections, and a 24 V AC control coil, making it suitable for use in motor control centers (MCCs), automation systems, HVAC applications, machinery, and industrial power distribution systems.
This model belongs to the compact S00 frame size and is rated for AC-3e/AC-3 duty up to 9 A, with a motor capacity of approximately 4 kW at 400 V AC, depending on operating conditions. It is widely used for small to medium motor control applications in industrial environments where reliable switching and compact design are required.
The integrated mirror contact elements provide a mechanically linked auxiliary feedback contact that reflects the main contact position. This is essential for PLC interlocking, safety circuits, and monitoring systems, ensuring accurate ON/OFF status confirmation for safe operation and diagnostics.
With robust screw terminal connections, the 3RT2016-1AB018K ensures secure wiring, vibration resistance, and easy installation inside control panels, supporting long-term durability and stable performance in industrial environments.
