Function

The Siemens 3TB4222-0XG2 contactor’s primary function is to switch an electrical power circuit on or off. When the 110V AC coil is energized, the main contacts close, allowing current to flow to the connected load. The auxiliary contacts simultaneously change their state (NO closes, NC opens), providing signals for control and monitoring circuits. This makes it an essential component for automated control systems, providing the interface between low-power control signals and high-power electrical loads.

Application

• Motor control for pumps, fans, conveyors, and compressors
• HVAC systems
• Industrial machinery
• Lighting control in large facilities
• Heating element control
• Automation and control panels
