Siemens 6SE7032-7EB87-2DA1 SIMOVERT MASTERDRIVES Braking Unit
A 170 kW braking unit for 510–650 V DC-link applications in the SIMOVERT MASTERDRIVES platform.
Product Profile
6SE7032-7EB87-2DA1 is a Siemens SINAMICS / SIMOVERT MASTERDRIVES braking unit for a 510–650 V DC-link range. The catalog execution is rated at 170 kW and uses IP20 protection.
The braking unit manages regenerative energy through the engineered braking-resistor circuit. Selection therefore depends on DC-link compatibility, resistor data, duty cycle, cabinet cooling and protective coordination.

- Confirm cabinet clearances, airflow, fusing, protective earth and insulation coordination.
Applications
- Dynamic deceleration of high-inertia industrial drives.
- Regenerative-energy handling where line regeneration is not used.
- Like-for-like maintenance in documented SIMOVERT MASTERDRIVES cabinets.
FAQ
Can 6SE7032-7EB87-2DA1 be chosen from motor power alone?
No. DC-link range, regenerative energy, braking duty, resistor design, cabinet cooling and the complete drive article must be checked together.
Which resistor information is needed for 6SE7032-7EB87-2DA1?
Provide resistance, continuous and peak energy ratings, thermal protection, cable data and the installed braking cycle.
Is 6SE7032-7EB87-2DA1 suitable for installation outside a cabinet?
Its IP20 execution requires the enclosure, access protection, cooling and environmental controls defined for the installation.
What must be checked before replacing 6SE7032-7EB87-2DA1?
Inspect the resistor, DC-link wiring, fuses, contactors, thermal trips, grounding and the fault history that led to removal.
Can a different MASTERDRIVES braking unit replace 6SE7032-7EB87-2DA1?
Only after Siemens documentation confirms DC-link compatibility, braking capacity, mechanics, interfaces and protection coordination.
What tests follow installation of 6SE7032-7EB87-2DA1?
Verify insulation and connections first, then observe DC-link behavior, resistor current, temperatures, alarms and controlled deceleration.
