The Siemens 3RT2016-1BB41 is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors and industrial loads. It comes 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. It is commonly used in small to medium motor control applications where stable switching and PLC compatibility are required.
According to Siemens official specifications, the 3RT2016-1BB41 includes a 3-pole main switching system, 1 NO auxiliary contact, and screw terminal connections, ensuring reliable wiring and stable operation in control panels.
The integrated mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for PLC interlocking, safety circuits, and system monitoring. This ensures that the controller can confirm whether the contactor is actually energized or de-energized, improving operational safety and diagnostics.
With robust screw terminals, installation is secure and vibration-resistant, making it suitable for long-term industrial use in harsh environments.
