Siemens 3TB4101-0XH0 Contactor – 48V AC, 12A, 5.5kW, Size 0, 1NC Auxiliary Contact Original Brand New

Overview

The Siemens 3TB4101-0XH0 is a reliable and high-performance contactor designed for controlling electric motors and other electrical loads. This specific model is engineered for use in alternating current (AC) systems operating at 50 Hz with a control voltage of 48V AC. It’s rated for a nominal current of 12A at 400V AC3, making it suitable for motor applications up to 5.5 kW. Its compact size 0 design and screw connections ensure easy installation and secure wiring. The integrated 1 NC (normally closed) auxiliary contact provides additional control and feedback options for your system.

Benefit

• Dependable Performance: Engineered by Siemens, a global leader in industrial automation, ensuring high quality and longevity.
• Efficient Power Control: Perfectly suited for managing motor loads up to 5.5 kW, optimizing energy usage and system efficiency.
• Space-Saving Design: The compact size 0 footprint allows for installation in tight spaces, ideal for crowded control panels.
• Simple & Secure Installation: Screw terminals make wiring straightforward and provide a robust, reliable connection.
• Enhanced Control: The built-in 1NC auxiliary contact offers flexible control possibilities, such as interlocking or status indication.

Function

The Siemens 3TB4101-0XH0 functions as an electrically operated switch. When the 48V AC control voltage is applied to its coil, it closes its main contacts, allowing power to flow to the connected load. When the control voltage is removed, a spring opens the contacts, interrupting the power flow. The 1NC auxiliary contact changes its state in tandem, opening when the main contacts close and closing when the main contacts open. This action is crucial for safety and system logic.
