Function

The Siemens 3TB4001-0XH0 contactor’s primary function is to act as a remote-controlled electrical switch. When the 48V AC coil is energized, it generates a magnetic field that pulls a core, closing the main power contacts. This allows electricity to flow to the connected load (e.g., a motor). When the coil is de-energized, the contacts open, safely cutting off power. The integrated NC auxiliary contact operates simultaneously but in the opposite manner, opening when the main contacts close.
