Siemens 3TB4022-0XC2 Contactor: 24V AC, 9A, 4kW, with 1NO+1NC Auxiliary Contact Original Brand New

Overview

The Siemens 3TB4022-0XC2 is a robust and reliable contactor designed for controlling electric motors and other loads in industrial applications. This specific model operates on an AC supply and is suitable for both 50 Hz and 60 Hz frequencies. It features a 24V AC coil for efficient control and is rated for a 9A current at 400V AC3, making it ideal for loads up to 4 kW. The compact size 0 design and screw connections make installation and wiring straightforward. A key feature is the integrated 1 normally open (NO) and 1 normally closed (NC) auxiliary contacts, providing flexibility for control and signaling circuits.

Benefit

• Reliable Performance: Engineered by Siemens, a leader in industrial automation, ensuring high quality and a long operational lifespan.
• Energy Efficient: The 24V AC coil offers a lower power consumption compared to higher voltage coils, reducing operating costs.
• Versatile Application: Suitable for a wide range of applications, including motor control, lighting, and heating systems.
• Enhanced Control: The auxiliary contacts (1 NO + 1 NC) allow for easy integration into complex control systems, such as interlocking and feedback loops.
• Simple Installation: The screw terminals provide a secure and reliable connection, simplifying the wiring process.

Function

The Siemens 3TB4022-0XC2 contactor acts as an electrically operated switch. When the 24V AC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing power to flow to the connected load. When the coil is de-energized, the contacts open, interrupting the power. The auxiliary contacts switch simultaneously with the main contacts, providing signals for other parts of the control circuit.
