Function

The Siemens 3RT2018-1BM41 power contactor is an electromechanical switching device used primarily for ON/OFF switching of 3-phase AC motors and heating loads. When the 220 V DC control voltage is applied to the coil, the main power contacts close, allowing current (up to 16 A to flow to the load. The auxiliary contact provides a signal indicating the contactor’s status to the control system. It is specifically designed for the performance range up to 7.5 kW in standard industrial environments.
