Function

The Siemens 3RT2018-2AP61 power contactor serves as an electromechanical switch that controls the flow of electrical power to a load, such as an electric motor, heating element, or lighting circuit. When the coil is energized by the control voltage (220V/240V AC), the main contacts close, allowing power to flow to the connected equipment.

The integrated auxiliary contact provides a signal indicating the status of the main contacts (e.g., to a PLC or another control device). The spring-loaded terminals ensure a reliable, maintenance-free connection even in high-vibration applications.

Application

• Motor control and switching
• Pump and fan control systems
• Heating, ventilation, and air conditioning (HVAC) systems
• Industrial automation and machinery
• Lighting control systems
