3TF6833-1DB4 SIEMENS

The 3TF6833-1DB4 Siemens contactor is a robust and reliable switching device designed for demanding industrial applications. It is a size 14, 3-pole contactor specifically engineered for AC-3 duty, making it suitable for switching standard squirrel-cage motors. With a substantial power rating of 335kW at 400/380V (and also rated for 690V systems), this contactor can handle high-power motor control requirements. The integrated auxiliary switch block features a 33 configuration, providing 3 normally open (NO) and 3 normally closed (NC) contacts for versatile control and feedback signaling. This contactor is designed for use in reversing applications when paired with a 3TC4417-4A reversing contactor, enabling efficient motor direction control. It incorporates a series resistor DC economy circuit operating at 24V DC, which reduces the holding power required after the contactor has closed, minimizing energy consumption and heat generation. This feature enhances the contactor's energy efficiency and extends its operational lifespan. The 3TF6833-1DB4 is ideal for applications requiring frequent switching and high operational reliability. Its durable construction and advanced features make it a dependable choice for motor control in various industrial settings. Siemens contactors are known for their quality and performance, ensuring long-term reliability and minimal downtime.
