Function

The Siemens 3RT2028-1AD00 serves as a remotely operated switch for controlling the power to an electrical load. When the 42 V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected device. De-energizing the coil opens the contacts, interrupting the power. This makes it a crucial component in motor starters, control panels, and automation systems for safely and efficiently managing electrical circuits.
