Braking Resistor

During train braking, the motor starts generating electric power. When it is not possible to store or re-generate it, this power must be dissipated through the resistor via natural or forced convection.

Our technology allows you to dissipate the highest power in small space with the lightest solutions. Our low-noise, forced-cooled resistors guarantee an outstanding reliability and low maintenance costs.

  • Fully customized solutions: ohmic value range up to 20 Ohm
  • Continuous or intermittent operations with power range up to 2,6 MW/module
  • Suitable for harsh and extreme environment with IP20 protection degree
  • Thermal sensors available to monitor resistor operations
