The Siemens 3RT2017-1AF01 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 is equipped with mirror contact elements, screw terminal connections, and a 110 V AC control coil (50/60 Hz), making it suitable for 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 ideal for small industrial motor switching applications requiring dependable performance and easy panel integration.
It includes 1 NO auxiliary contact, which is used for control feedback, interlocking, and PLC signaling in automation systems.
The mirror contact elements ensure mechanically linked feedback of the main contacts, which is critical for safety circuits and monitoring systems, allowing controllers to verify the true ON/OFF status of the contactor for safe machine operation.
With screw terminals, the device ensures secure wiring, vibration resistance, and long service life in industrial environments.
