Function

A contactor is an electrically controlled switch used for switching an electric power circuit. When the 24V AC coil of the Siemens 3TB4101-0XC1 is energized, it creates a magnetic field that closes the main power contacts, allowing current to flow to the load. When the coil is de-energized, a spring returns the contacts to their open position, interrupting the circuit. The auxiliary contact changes state simultaneously, providing a signal that indicates the status of the main contacts.

Application

• Motor starters and control panels
• HVAC systems
• Pump control
• Lighting control circuits
• Industrial machinery
