Siemens 3TB3901-0XG0 Contactor AC 50 Hz, 36V, 6A, 2.2kW, Size 0 with 1 NC Auxiliary Contact Original Brand New

Overview

The Siemens 3TB3901-0XG0 is a high-performance, reliable AC contactor designed for efficient motor control and power switching in various industrial environments. This specific model is engineered to operate on a 36V AC, 50 Hz control voltage, making it suitable for applications where a low control voltage is required for safety and system design. It is rated for a 6A current at 400V for AC-3 utilization, and can handle a 2.2 kW motor load, ensuring robust performance for light to medium-duty applications. The contactor is a compact size 0, which saves valuable panel space, and features one normally closed (NC) auxiliary contact for enhanced control and feedback functionality. The secure screw connection terminals provide a reliable and straightforward installation process.

Benefit

• Space-Saving Design: The compact size 0 footprint allows for efficient use of space within control cabinets and electrical panels.
• Enhanced Control: The integrated normally closed (NC) auxiliary contact provides an additional switching point for interlocking, signaling, or control circuit logic.
• Safe and Efficient Operation: Designed for 36V AC control circuits, it meets specific safety standards and is ideal for systems where low control voltage is a requirement.
• Easy Installation: The screw connection terminals ensure a secure and simple wiring process, reducing installation time and effort.
• Broad Application Range: Suitable for a wide variety of applications, including HVAC systems, pumping stations, conveyor belts, and other general-purpose motor control tasks.

Function

The Siemens 3TB3901-0XG0 contactor serves as an electrically operated switch, primarily used for remotely controlling electric motors and other loads. Its core functions include:

1. Motor Switching: Safely and reliably switches on and off three-phase motors.
2. Power Circuit Control: Establishes and interrupts a power circuit in response to a control signal from a push-button, PLC, or other control device.
3. Auxiliary Signaling: The 1 NC auxiliary contact can be used to provide feedback to a control system or to interlock other devices, ensuring a safe sequence of operations.
4. Overload Protection Integration: Designed to be paired with thermal overload relays (sold separately) for complete motor protection against overcurrents.
