🔹 Power Contactor with Mirror Contact Elements, Spring-Loaded Terminals, DC Coil – 3RT2016-2BB41

🔹 Product Description

The Siemens 3RT2016-2BB41 is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors up to 4 kW at 400 V AC. It features mirror contact elements, spring-loaded (push-in) terminals, and a 24 V DC control coil, 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 9 A, making it ideal for small motor control applications requiring fast wiring and PLC compatibility.

It includes 1 NO auxiliary contact, which is used for control feedback, interlocking, and signaling in automation systems.

The mirror contact elements ensure mechanically linked feedback of the main contacts, which is critical for safety circuits and PLC monitoring, allowing systems to confirm whether the contactor is truly ON or OFF during operation.

With spring-loaded terminals, wiring becomes faster, vibration-resistant, and maintenance-friendly compared to traditional screw terminals, making it highly suitable for modern industrial panel designs.
