HLR01.1N-44K0-N03R3-B-007-NNNN

The Bosch Rexroth Indramat HLR01.1N-44K0-N03R3-B-007-NNNN from the HLR Brake Resistors series by Bosch Rexroth Indramat delivers a continuous output of 44 kW with a fixed resistance of 3.3 Ω and a DC Bus Nominal Voltage of 700 V DC. This brake resistor can absorb regenerative peaks up to 2000 kW during rapid deceleration, safeguarding the variable frequency drive from overvoltage events. Engineered for heavy-duty industrial environments, it supports natural convection cooling with a minimum airflow of 150 m³/h to dissipate generated heat. A comprehensive specification sheet details the maximum cable diameter for conduit connections and precise mounting instructions.

The robust enclosure features a protection rating of IP23, preventing ingress of objects over 12.5 mm and spray water at angles less than 60° from vertical. Its casing is coated with an insulating layer to limit heat accumulation and resist corrosion in harsh factory conditions. Installers must observe clearances from combustible materials to avoid heat-related damage and ensure uninterrupted brake resistor operation. Comprehensive documentation accompanies each unit, detailing thermal curves, dimensional drawings, and safety guidelines.

With a compact form factor and global shipping availability, the HLR01.1N-44K0-N03R3-B-007-NNNN integrates seamlessly into existing servo drive layouts. A one-year warranty underscores Bosch Rexroth Indramat’s commitment to quality and reliability in industrial braking applications. This HLR Brake Resistor enhances system longevity, reduces maintenance intervals, and optimizes drive performance across automation platforms.
