Function

The Siemens 3RT2036-1CL24-3MA0 serves as an electromechanical switch. When its 230V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). When the coil is de-energized, a spring mechanism opens the contacts, interrupting the power. The 2 NO and 2 NC auxiliary contacts can be used for interlocking circuits, signaling the status of the main contactor (e.g., “on” or “off”), or controlling other parts of the automation system.

Application

• Motor starters (direct-on-line, reversing)
• Pump control systems
• Ventilation and fan systems
• Conveyor systems
• General industrial switching tasks
