Functions

The Siemens 3TB3922-0XD2 contactor’s primary function is to serve as an electrically controlled switch. When the 42 V AC control voltage is applied to the coil, the main contacts close, allowing power to flow to the connected load (e.g., a motor or heater). Simultaneously, the auxiliary contacts change state—the NO contact closes and the NC contact opens—providing feedback for control systems, interlocking circuits, or signaling. This functionality makes it a core component in motor starters, control panels, and automation systems.
