Siemens 3TB4322-0XC2 Contactor 24V AC, 22A, 11kW with Auxiliary Contacts Original Brand New

Overview

The Siemens 3TB4322-0XC2 is a robust and reliable AC contactor designed for industrial applications. It operates on a 24V AC supply and is rated for 22A at 400V, capable of handling motor loads up to 11kW. This contactor is a size 1 device and features screw terminals for secure and easy installation. It’s ideal for controlling electrical circuits, particularly in motor control applications.

Benefit

• High Performance: Efficiently handles inductive loads up to 11kW, ensuring reliable operation for motors and other heavy-duty equipment.
• Enhanced Safety: Equipped with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact, providing greater flexibility for safety interlocks and signaling circuits.
• Durable Design: The robust construction of the Siemens 3TB series ensures a long operational life and high reliability in demanding industrial environments.
• Easy Installation: Screw connections allow for straightforward and secure wiring, reducing installation time and potential wiring errors.
• Brand Trust: As a Siemens product, the 3TB4322-0XC2 guarantees quality, consistency, and compliance with international standards.

Function

The contactor functions as an electrically operated switch. When the 24V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). Simultaneously, the auxiliary contacts change state: the NO contact closes and the NC contact opens. This functionality is essential for automation, remote control, and safety circuits, enabling control over high-power circuits from a low-power control signal.
