3TX7402-3U SIEMENS

The 3TX7402-3U Siemens surge suppressor is an RC element meticulously designed to mitigate voltage spikes and transient surges, thereby safeguarding sensitive electronic components from potential damage. Operating within a voltage range of 240-400V AC, this surge suppressor effectively dampens overvoltage occurrences, ensuring the reliable and consistent performance of connected equipment. Its primary application lies in mounting directly to the coil terminal of contactors, specifically those within sizes S0 to S2, offering a streamlined and integrated surge protection solution. By incorporating a cable spacer, the design facilitates organized wiring and prevents unwanted contact between conductors, further enhancing safety and operational efficiency. This RC element effectively reduces electromagnetic interference (EMI) and radio frequency interference (RFI), contributing to a cleaner and more stable electrical environment. The surge suppressor extends the lifespan of contactors and other connected devices by minimizing stress caused by voltage transients. Its robust construction ensures durability and reliable performance in demanding industrial environments. Easy to install and maintain, the 3TX7402-3U provides a cost-effective solution for enhancing the reliability and longevity of electrical systems. This device is an essential component for any application where voltage surge protection is critical.
