When the DC link voltage rises excessively, there is a concrete risk to damage costly traction chain components. To avoid this, the resistor dissipates the power peaks keeping the DC link voltage stable. In DC networks, this function is provided by the braking resistor.

We designed our overvoltage protection resistors with state-of-the-art design and manufacturing technologies to achieve the most demanding performances in the smallest volume.

• High Energy absorption up to 3 MJ
• Light and compact units
• Suitable for outdoor installation
