Overview

The Siemens 3TB4422-0XK1 is a high-performance contactor designed for reliable switching of electrical loads in industrial and commercial applications. This device operates on a 120V AC, 60 Hz coil voltage and is rated for a maximum current of 32A at 400V AC3. With a power rating of 15 kW, it is well-suited for controlling motors, lighting, heating systems, and other high-power equipment. The Size 2 compact design makes it ideal for space-constrained installations.

Key Features & Benefit

• High Performance: Provides efficient and reliable switching for a wide range of electrical loads.
• Built-in Auxiliary Contacts: Includes one normally open (1 NO) and one normally closed (1 NC) auxiliary contact for additional control and signaling functions.
• Easy Installation: Features screw terminals for secure and straightforward wiring.
• Durable Construction: Built with high-quality materials to ensure a long service life and withstand harsh industrial environments.
• Versatile Application: Suitable for use in various applications, including HVAC systems, pumping stations, and manufacturing equipment.

Function

The Siemens 3TB4422-0XK1 contactor acts as an electrically operated switch. When the 120V 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 integrated 1 NO + 1 NC auxiliary contacts can be used to provide feedback to a control system or to interlock with other devices, enhancing the overall safety and functionality of the circuit.
