Function

The Siemens 3RT2017-1BM41 power contactor is primarily used to switch electrical loads on and off. When a 220 V DC voltage is applied to its coil, it generates a magnetic field that pulls the main contacts closed, allowing current to flow to the connected load (e.g., a motor). When the coil voltage is removed, a spring forces the contacts open, interrupting the power. The integrated 1 NO auxiliary contact changes its state in tandem with the main contacts, providing a signal that can be used for interlocking, status monitoring, or activating other control circuits.
