🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, DC Coil – 3RT2016-1BB418K

🔹 Product Description

The Siemens 3RT2016-1BB418K 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 DC 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-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 commonly used for small to medium motor control applications where reliable switching and PLC feedback are required.

The integrated mirror contact elements provide a mechanically linked auxiliary feedback contact that reflects the true position of the main contacts. This is important for PLC interlocking, safety circuits, and machine monitoring, ensuring that the system can verify whether the contactor is actually ON or OFF for safe operation.

With robust screw terminals, the contactor ensures secure wiring, vibration resistance, and easy installation inside control panels, supporting long-term reliability in industrial environments.
