Function and Application

The magnet coil is the core component of a contactor’s electrical circuit. When a 42V DC control signal is applied to the coil’s terminals, it generates a magnetic field. This field pulls the armature, which is mechanically linked to the main contacts, causing them to close. This action allows the high-current power circuit to be switched on or off. The Siemens 3TY6443-0BD4 is therefore vital for:

• Motor control circuits
• HVAC systems
• Lighting control
• Automation and machine control
• Any industrial application using 3TB44 or 3TC44 contactors
