The Stotz S&J du/dt output filter NOCH0070-60 from ABB is a specialized relay designed to optimize the performance of motors in conjunction with frequency converters. This product is particularly useful for reducing vibrations on motor cables, allowing for longer cable lengths without compromising the integrity of the motors. Additionally, the filter helps to limit the voltage rise value dU/dt, which is especially important when operating motors with weak insulation. Using this filter can extend the lifespan of the motors and enhance operational safety by minimizing the effects of electrical disturbances. The Stotz S&J du/dt output filter is a reliable solution for applications that require precise control and stability.

• Reduces vibrations on motor cables
