Function

The Siemens 3TB4422-0XG0 functions as an electrically controlled switch used for power circuits. When the 36V AC coil is energized, it generates a magnetic field that pulls the main contacts together, allowing high-power current to flow through the device to a connected load, such as an electric motor. When the coil is de-energized, the contacts spring open, safely interrupting the power flow. The auxiliary contacts switch simultaneously with the main contacts, providing signals for control and monitoring systems.

Application

• Motor control and starting in industrial machinery
• HVAC systems and pumps
• Conveyor systems
• Compressors
• Lifting and hoisting equipment
• Lighting control systems
• Industrial automation and control panels
