🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, DC Coil – 3RT2016-1FB443MA0

🔹 Product Description

The Siemens 3RT2016-1FB443MA0 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 comes with mirror contact elements, screw terminal connections, and a 24 V DC control coil with integrated diode, 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 and switching applications in industrial environments.

A key highlight of this variant is the inclusion of 2 NO + 2 NC auxiliary contacts, which provide enhanced switching flexibility for control circuits, interlocking logic, and feedback signals in PLC-based automation systems.

The integrated mirror contact elements ensure mechanically linked feedback of the main contacts, which is critical for safety circuits, machine interlocking, and status monitoring, allowing systems to verify whether the contactor is actually ON or OFF.

With screw terminals, installation remains secure, vibration-resistant, and suitable for long-term industrial use.
