Product Description:
The HLR01.1N-10K0-N18R0-A-007-NNNN brake resistor is produced by Bosch Rexroth Indramat and belongs to the HLR Brake Resistors series. It is installed on the DC bus of an inverter so that excess regenerative energy from decelerating servo axes is converted into heat instead of raising the intermediate-circuit voltage. By providing a defined resistance path, the unit safeguards drive controllers against overvoltage faults during dynamic braking events in automated machinery and production lines.
The resistor’s continuous braking capacity is 10 kW, meaning it can dissipate this heat level for an unlimited duty cycle without exceeding its thermal limit. Its electrical opposition is specified at 20.2 Ω; this value determines how much current flows for a given DC-bus voltage and therefore sets the rate of energy conversion. Physical dimensions influence mounting space: depth is 490 mm and width is 600 mm, allowing it to fit alongside power modules inside standard cabinets. When a fast stop is required, the device may be energized for up to 32 s at maximum load before a cooling pause is needed. During such a peak event, it can absorb a cumulative energy of 1080 kWs, protecting the drive system from transient surges produced by high-inertia loads. Cable lugs or bars up to 10 mm² can be connected to its terminals so wiring can handle the required current without overheating.
The short-term overload ceiling reaches 33 kW, giving extra margin for emergency stops that exceed the continuous rating. A mass of 22 kg adds thermal inertia, slowing internal temperature rise during brief high-power cycles and reducing the frequency of forced cooldowns. The overall height is 270 mm, so multiple resistors can be stacked vertically when panel footprint is limited while still meeting the spacing rules specified for natural convection airflow.
