Function

The Siemens 3RT2015-2AB02 power contactor functions as an electrically operated switch. When the 24V AC control voltage is applied to the coil, it creates an electromagnetic field that pulls the main contacts together. This action closes the circuit, allowing power to flow to the connected load (e.g., an electric motor). When the control voltage is removed, the contacts open, interrupting the power flow and safely de-energizing the load. The integrated 1NC auxiliary contact provides a signal for control and monitoring circuits, indicating the open state of the main contacts.

Ideal Application

• Motor control and protection in industrial machinery
• Heating, ventilation, and air conditioning (HVAC) systems
• Pump and compressor control
• Conveyor systems
• Lighting control panels
• Automation systems and building management
