🔹 Power Contactor with Mirror Contact Elements, Screw Terminals, AC Coil – 3RT2017-1AB018K

🔹 Product Description

The Siemens 3RT2017-1AB018K is a SIRIUS 3RT2 series 3-pole power contactor designed for reliable switching of three-phase motors up to 5.5 kW at 400 V AC. It features mirror contact elements, screw terminal connections, and a 24 V AC control coil (50/60 Hz), 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 12 A, making it suitable for slightly higher load applications compared to 9A contactors.

Based on Siemens SIRIUS technical data, the 3RT2017 series supports 12 A AC-3 rating and 5.5 kW motor switching at 400 V AC, with screw terminal construction for secure industrial wiring and long-term durability.

The integrated mirror contact elements provide mechanically linked feedback of the main contacts, which is essential for PLC interlocking, safety circuits, and system monitoring, ensuring that the controller can reliably detect whether the contactor is actually ON or OFF.

With screw terminals, installation remains secure, vibration-resistant, and suitable for harsh industrial environments where long-term reliability is critical.
