Function

The Siemens 3RT2036-1AK64-3MA0 functions as an electrically operated switch, primarily used for remotely controlling the flow of power to a motor. When the coil is energized by the 110V/120V AC control voltage, the main contacts close, allowing current to flow to the connected load. The captive 2 NO + 2 NC auxiliary contacts change state simultaneously, providing signals for other parts of the control system, such as interlocks or status indicators.

Application

• Motor control and protection in industrial machinery
• Heating, ventilation, and air conditioning (HVAC) systems
• Pump and fan control
• Automation and process control systems
• General power switching applications in industrial settings
