Siemens 3TB4010-0XG2 Contactor: 110V AC, 9A, 4kW – Size 0 with 1 NO Auxiliary Contact Original Brand New

Overview

The Siemens 3TB4010-0XG2 is a high-performance, robust contactor designed for reliable switching of electrical loads, particularly in motor control applications. This size 0 contactor is engineered for use with AC loads, handling up to 9A and 4kW at 400V (AC-3 rating). Its compact design and user-friendly screw connections make it an excellent choice for a wide range of industrial and commercial applications. The integrated 1 NO (Normally Open) auxiliary contact provides essential feedback and control capabilities, allowing for integration into complex control circuits.

Key Benefit

• Reliable Performance: Siemens quality ensures long-lasting and dependable operation, even in demanding industrial environments.
• Energy Efficient: Optimized design for efficient switching, reducing power consumption during operation.
• Easy Installation: Features clear screw terminals for quick and secure wiring, minimizing installation time and effort.
• Versatile Application: Suitable for a broad spectrum of AC motor control, lighting, heating, and other inductive or resistive load switching tasks.
• Enhanced Control: The built-in 1 NO auxiliary contact offers flexibility for interlocking, signaling, and sequence control circuits.

Functionality

The Siemens 3TB4010-0XG2 functions as an electromagnetically operated switch. When the 110V AC coil is energized, it creates a magnetic field that closes the main power contacts. This allows current to flow to the connected load, such as an electric motor. The auxiliary contact also changes state, providing a signal to a PLC, relay, or other control component. When the coil is de-energized, the magnetic field collapses, and a spring forces the contacts back to their open position, safely interrupting the circuit.

Application

• Motor Control: Starting, stopping, and reversing motors in machinery, pumps, and fans.
• Lighting Systems: Switching large lighting banks in commercial and industrial buildings.
• Heating Elements: Controlling power to heating elements in ovens, furnaces, and HVAC systems.
• Capacitor Banks: Switching capacitor banks for power factor correction.
• General Load Switching: Remotely controlling various electrical loads in automated systems.
