Product Description:

The HLR01.1N-03K5-N19R0-A-007-NNNN is a brake resistor produced by Bosch Rexroth Indramat as part of the HLR Brake Resistors series. Integrated into the DC link of motion-control drives, the resistor provides a controlled discharge path for regenerative current so that axis deceleration does not raise the intermediate circuit voltage beyond safe limits. It uses construction type B, which provides a predefined mounting footprint for panel installation in industrial automation cabinets.

With a continuous dissipation capability of 3.5 kW, the HLR01.1N-03K5-N19R0-A-007-NNNN can accept steady regenerative flow from medium-power axes without thermal overload. The resistor is matched to DC links up to 700 V, so it pairs directly with converters that operate on a 540 to 750 V intermediate circuit. Its nominal resistance of 19.0 Ω sets the current drawn during each braking event, while the design permits a peak braking power of 31 kW for short intervals. A stored-energy rating of 252 kWs indicates how much kinetic or potential energy can be absorbed in a single stop before the element reaches its permitted temperature rise. These electrical values allow predictable drive sizing and help protect the bus capacitors from excessive voltage.

The metal enclosure measures 300 mm in width, 490 mm in depth, and 270 mm in height, yielding a compact block that can be placed beside frequency inverters. It weighs 9.5 kg, which remains manageable during cabinet assembly. An ingress protection level of IP20 indicates that fingers and solid objects larger than 12 mm are blocked, while airflow remains available for natural convection. At least 1000 mm of top clearance is recommended to maintain a vertical heat plume and prevent overheating of adjacent devices. When the continuous power limit is observed, the B-type housing keeps heat within the expected operating range during braking duty.
