Siemens 3TB4222-0XU0 Contactor 16A, 7.5kW, 240V AC Coil Original Brand New

Overview

The Siemens 3TB4222-0XU0 is a high-performance AC contactor designed for reliable switching of electrical loads in industrial and commercial applications. This Size 1 contactor is engineered for use with a 240V AC coil at 50Hz, making it a robust solution for motor control and power switching. With a rated operational current of 16A for AC-3 duty at 400V and a power rating of 7.5kW, it’s suitable for a wide range of motor starting and general-purpose switching tasks. The unit includes built-in auxiliary contacts (1 normally open, 1 normally closed) for enhanced control circuit integration and monitoring. The screw connection terminals ensure a secure and straightforward installation process.

Benefit

• Robust Performance: Rated for demanding AC-3 duty, ensuring long-term reliability for motor applications.
• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC contacts simplify wiring and reduce the need for external contact blocks.
• Compact Size: The Size 1 design is space-efficient, allowing for easy integration into control panels and cabinets.
• Secure Connections: Screw terminals provide a reliable and durable electrical connection.
• Wide Application Range: Ideal for controlling motors, lighting circuits, heating systems, and other general-purpose electrical loads.
• Siemens Quality: Manufactured by Siemens, a global leader in industrial automation, guaranteeing a high standard of quality and durability.

Function

The Siemens 3TB4222-0XU0 contactor serves as an electrically operated switch that controls a power circuit. When the 240V AC 50Hz coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., a motor). The auxiliary contacts simultaneously change their state (NO becomes closed, NC becomes open), providing feedback and control signals to the larger control system. This functionality is crucial for automation, safety interlocks, and sequential operations in machinery.
