• Enhanced Durability: Built with high-quality materials to withstand the demands of continuous operation in industrial environments.
• Reduced Downtime: Quick and easy replacement allows for minimal interruption to your operations, maximizing productivity.

Function

The magnet coil is the heart of an electrical contactor. When energized by the specified voltage (in this case, 120V AC), it generates a magnetic field that pulls the movable contact armature. This action closes the main power contacts, allowing current to flow to the connected load, such as a motor. When the voltage is removed, the magnetic field collapses, and the armature returns to its original position, opening the contacts and interrupting the circuit. The 3TY7403-0AK2 ensures this critical switching function is executed reliably and safely.

Application

This magnet coil is essential for maintaining electrical control systems in a wide range of applications, including:

• Industrial automation and control panels
• Motor control centers (MCCs)
• HVAC systems
• Pump control
• Lighting control systems
• Any machinery utilizing the compatible Siemens contactor series
