Function

The Siemens 3RT7026-1AF00 functions as an electromagnetically operated switching device. When the 110V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load. When the coil is de-energized, the contacts open, interrupting the power. This makes it a crucial component in motor control circuits, machinery, and automation systems.
