Description
Product Description
The Siemens 6SE7021-0ES87-1FE0 is a high-performance braking resistor engineered for use with SIMOVERT MASTERDRIVES and compatible Siemens drive systems. Designed to dissipate regenerative energy generated during motor deceleration, this resistor helps protect the DC-link from overvoltage conditions while ensuring stable and reliable drive operation. With a resistance value of 40 Ω and a rated braking power of 6.25 kW, it provides efficient energy absorption for demanding industrial motion control applications.
Built for continuous operation in industrial environments, the resistor is ideal for machine tools, cranes, conveyors, material handling systems, packaging machinery, printing equipment, and automated production lines where frequent braking cycles and rapid deceleration are required.
