Function

The Siemens 3RT2017-2AF01 functions as an electrically controlled switch. When the 110 V AC coil is energized, it closes the three main poles, allowing power to flow to the connected motor or load. Simultaneously, the 1 NO auxiliary contact closes, which can be used for feedback or control logic within the system. It is primarily used for switching electric motors on and off, or for controlling other resistive and inductive loads.
