Siemens 3RT2017-1BF41 SIRIUS Power Contactor, 12A, 5.5kW/400V, 3-Pole, 110V DC Coil, 1NO Aux, Size S00, Screw Terminal Original Brand New

Overview: Siemens 3RT2017-1BF41 SIRIUS Power Contactor

The Siemens 3RT2017-1BF41 is a high-performance SIRIUS 3RT2 series power contactor designed for switching motors and other electrical loads in industrial control applications. This compact, 3-pole contactor is rated for $12\text{ A}$ (AC-3e/AC-3) and a power output of $5.5\text{ kW}$ at $400\text{ V}$. It features a reliable $110\text{ V DC}$ operating coil for global use and includes a factory-integrated $1\text{ NO}$ auxiliary contact in its smallest frame size, S00. Its robust screw terminals ensure a secure and durable electrical connection. As part of the SIRIUS modular system, the 3RT2017-1BF41 offers optimal coordination and flexibility for building efficient load feeders.
