Product Description:
The HLR01.1N-66K0-N02R7-A-007-NNNN brake resistor is produced by Bosch Rexroth Indramat and belongs to the HLR Brake Resistors series. In regenerative drive axes, this component converts surplus kinetic energy into heat so DC-bus voltage stays within safe operating limits during deceleration. It is intended for cabinet installation alongside IndraDrive power sections and integrates with automation systems that require controlled energy dissipation instead of line feedback. This operating role is useful in applications with frequent braking, including conveyors, handling axes, and other high-inertia motion systems.
The resistor can dissipate a continuous thermal load of 66 kW, while short surges up to 144 kW are supported during rapid stopping sequences. Its element has a nominal resistance of 3.1 ohms, which sets the current drawn from the shared DC link at a given voltage. A permitted on-time of 48 s per cycle matches the thermal capacity of the resistor assembly, and the ceramic grid can absorb as much as 6970 kWs before its temperature limit is reached. The housing measures 490 mm in depth and 710 mm in height, and free-assembly mounting allows the unit to be fixed to cabinet panels or frames when enough air gap is provided for convection and heat release.
A minimum cycle interval of 120 s allows the resistor to cool between load events and helps protect service life under repeated braking duty. With a weight of 80 kg, the assembly provides substantial thermal inertia for heavy braking patterns and stable placement inside the cabinet. The enclosure is rated IP20, so it must be installed inside a protected cabinet but remains finger-safe after wiring. Its front width of 795 mm sets cabinet bay spacing and airflow clearance relative to adjacent components, especially when multiple power devices share the same enclosure.
