Siemens 3RT2017-2KF41-1AA0 Power Contactor 12 A, 5.5 kW, 110V DC, Spring-Loaded Terminal, S00 Frame Original Brand New

Overview

The Siemens 3RT2017-2KF41-1AA0 is a high-performance power contactor designed for reliable switching of electrical loads in industrial applications. This 3-pole contactor is rated for AC-3e/AC-3 operation at 12 A and 5.5 kW at 400 V, making it ideal for controlling motors and other resistive or inductive loads. Its compact S00 frame size allows for space-saving installation, while the 110V DC control voltage with a wide operating range (0.7-1.25*Uc) ensures stable performance.

A key feature is the integrated suppressor diode, which protects sensitive control electronics, and the spring-loaded terminals, which provide fast, secure, and vibration-proof connections. This model is specifically engineered to be suitable for direct connection to PLC outputs and is designed for an upright mounting position.
