The 6SE7028-0ES87-2DA1 is a classic high-performance braking unit belonging to the Siemens SINAMICS / SIMOVERT MASTERDRIVES drive control family. Belonging to the Compact Plus construction type, this module allows for space-saving, high-density side-by-side installation inside control cabinets. It operates within a rated voltage range of 510V to 650V DC, delivers a substantial braking power capacity of 50 kW, and features an IP20 protection degree, requiring deployment in a protected industrial enclosure.
High-efficiency trip protection
High-density compact space
Flexible adaptation and adjustment
The primary function of this module is to connect in parallel to the drive's DC link, automatically intercepting and dissipating regenerative energy generated during motor deceleration, emergency stops, or overhauling loads to prevent system trips caused by DC overvoltage. It supports adjustable braking response threshold voltages via internal DIP switches, and the cable connection length to the inverter must be strictly limited to within 3 meters. The product comes complete with technical documentation on an included CD. As this model has been officially discontinued and phased out, it currently serves as a critical industrial spare part for legacy equipment, or as a transitional replacement during comprehensive drive system migrations to the modern SINAMICS S120 series.

Elevators & Lifts Industry
Used for braking control during car lowering or heavy-load lifting, dissipating the energy produced when the motor acts as a generator, ensuring safe and smooth elevator stops.
Port Machinery Industry
Used in the grab and trolley mechanisms of ship-to-shore (STS) cranes and rail-mounted gantry (RMG) cranes, dissipating massive regenerative energy during rapid container handling and frequent braking.
Mining & Extraction Industry
Used in large mine hoists and downhill high-inclination belt conveyors. It provides efficient and continuous electrical braking during heavy material downhill transport or emergency stops.
Rubber & Plastics Industry
Used in internal mixers, extruders, and high-power open mixing mills. It absorbs the kinetic energy of high-inertia rotors during sudden changes in material mixing resistance or emergency process stops.
Metallurgy & Steel Industry
Used in steel rolling mills and coiling machines. It stabilizes the DC link voltage during high-speed rolling, frequent reversals, and rapid deceleration of steel coils during winding.
First, live disconnection is strictly prohibited. Never use a contactor to disconnect the module while the DC link is energized, as this will cause severe arcing and destroy the equipment.
Second, cable lengths must be strictly limited. The cable to the inverter's DC link must not exceed 3 meters, and the cable to the braking resistor must not exceed 15 meters to prevent stray inductance and interference.
Third, prioritize maintenance after long-term inactivity. If the module has been stored unused for more than 1 year, the internal capacitors must undergo a forming (reconditioning) process before powering up.
Fourth, ensure proper heat dissipation and dust protection. With an IP20 protection rating, it must be installed in a well-ventilated, moisture-proof, and dust-free control cabinet, paired with correctly configured external braking resistors.
6SE7028-0ES87-2DA1 features an IP20 protection degree and supports adjusting the braking response threshold voltage via internal DIP switches, with the cable length to the inverter strictly limited within 3 meters. As this model has been discontinued and phased out, it currently serves primarily as an industrial spare part for legacy equipment, or as a transitional replacement during comprehensive drive system upgrades to the modern SINAMICS S120 series.
It is an industrial-grade braking unit module designed to consume regenerative energy generated during motor deceleration, protecting the inverter's DC link from overvoltage damage.
How to properly use a product like 6SE7028-0ES87-2DA1?
It must be connected in parallel to the DC link (positive and negative terminals) of the inverter and must be externally wired to a matching braking resistor to dissipate heat.
What structural design type does 6SE7028-0ES87-2DA1 belong to?
It features the Compact Plus construction type, making it ideal for spacesaving, side-by-side installation inside control cabinets.
What is the ingress protection rating of 6SE7028-0ES87-2DA1?
Its protection degree is IP20, meaning it must be installed inside a dust-free and moisture-protected industrial control cabinet.
Which braking resistor model is recommended for 6SE7028-0ES87-2DA1?
It is recommended to pair it with the corresponding standard braking resistor, model 6SE7028-0ES87-2DC0 (typically with a resistance of 8 ohms).
