HLR01.1N-08K5-N08R0-A-007-NNNN

The HLR01.1N-08K5-N08R0-A-007-NNNN, Bosch Rexroth Indramat, HLR Brake Resistors offers a robust brake resistor designed for high-energy applications. The unit features a Type B construction with a rugged steel-grid design that withstands repeated thermal cycling. Compatible with the HCS03 series of converters, it requires a dedicated brake chopper in the drive controller for proper operation. With a nominal 700 VDC bus voltage, the resistor seamlessly handles regenerative energy events without compromise.

The resistor delivers an Energy Consumption rating of 612 kWs and a Max Braking Power of 75 kW, sustaining a Braking Power Duration of 8.5 kW continuously. It supports a peak power rating of 82 kW for short transients and offers a conduction time of 8.2 s under full load. Housed in an IP20 enclosure, the device allows free-assembly mounting and mandates minimum clearance to dissipate heat via converter-driven airflow. Connectivity is ensured through a heavy-duty 6 AWG connection wire compliant with NFPA 79 and UL 508 A standards.

Engineers will appreciate the resistor’s compact footprint of 600 × 270 × 490 mm (W × H × D) and its manageable weight of 22 kg, facilitating straightforward installation. A factory-attached type-plate simplifies field verification of serial data and ratings. Backed by a one-year warranty, this brake resistor integrates seamlessly into automated drives, enhancing reliability and protecting your drive system from excessive regenerative loads.
