RUKO KEB-HM-41.0mm Wirewound Braking Resistor 150W 41 Ohm for KEB Combivert F5-K

When a variable frequency drive decelerates a motor, the regenerated energy must be dissipated safely to prevent overvoltage faults. The RUKO GMBH KEB-HM-41.0mm is a wirewound braking resistor built for exactly this task in KEB Combivert F5-K drive systems. It converts excess braking energy into heat, keeping the DC bus voltage within safe limits and ensuring reliable operation of your drive.

Who is it for

This resistor is intended for industrial automation engineers, panel builders, and maintenance technicians who integrate or service KEB Combivert F5-K drives. If your application involves frequent braking, hoisting, or fast deceleration, this component is essential for protecting the drive and maintaining process stability.
