Description
Product Description
The Siemens 6SE7028-0ES87-2DC0 is a heavy-duty braking resistor designed for SINAMICS and SIMOVERT MASTERDRIVES drive systems. Engineered to dissipate regenerative energy generated during motor deceleration, this resistor protects the DC link from overvoltage conditions while ensuring reliable braking performance in high-inertia industrial applications. The unit operates with DC link voltages from 510–620 V DC and features an 8 Ohm resistance value with a rated braking power of 12.5 kW and peak braking capacity of 75 kW.
Designed for demanding motion control environments, the 6SE7028-0ES87-2DC0 is ideal for CNC machinery, material handling systems, cranes, robotics, packaging equipment, printing presses, and automated production lines requiring frequent braking cycles and rapid deceleration.
