Product Description:

The HLR01.IN-17K0-N05R1-A-007-NNNN brake resistor is produced by Bosch Rexroth Indramat for the HLR Brake Resistors series. It is a passive load that channels surplus energy from the DC bus of a drive controller into heat. This process helps prevent DC-bus overvoltage during motor deceleration, direction changes, or downward load movements in automated machinery. Low-inductance film elements inside the housing distribute heat uniformly, which helps the resistor maintain consistent performance throughout its permitted ambient temperature range.

Its continuous braking capacity reaches 17 kW, allowing the connected drive to dissipate substantial regenerative power without triggering overvoltage faults. The resistance is 117 Ω, which determines the discharge current at a given DC-link voltage and affects stopping torque and thermal loading. Within one duty cycle, the element can sustain its rated load for up to 14 s before a passive cooling period is required. The housing has a front width of 1000 mm, which allows it to align with suitable rack columns and mounting supports. Its height is 270 mm, allowing the unit to share vertical mounting space with contactors, fuses, or filters inside a properly ventilated enclosure.

The installation depth is 490 mm, so ventilation paths must remain unobstructed along that dimension to maintain acceptable surface temperatures. During a single overload event, the resistor can absorb up to 1632 kWs of kinetic energy before requiring a cooldown period. The maximum on-time interval is 120 s, which limits prolonged loading and helps prevent thermal fatigue. A mass of 43 kg provides the heat capacity needed for short braking bursts and requires rigid mounting brackets when the assembly is secured to a backplate or floor-standing frame. The galvanized steel casing helps shield nearby electronics from radiated heat, while standard connection eyelets provide attachment points for wiring from the drive’s braking chopper.
