Function

The Siemens 3RT7036-1AQ00 contactor is a key component in any electrical control circuit. Its primary function is to electrically switch a high-power circuit by using a low-power control signal. When the 380 VAC 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, the contacts open, safely interrupting the power flow. This capability is essential for the start/stop control of motors, lighting, heating, and other high-current equipment.

Application

• Motor Starting and Stopping
• HVAC Systems
• Pumps and Fans
• Conveyor Systems
• Industrial Machinery
• General Load Switching
