Product Description:
The 16.BR.601-5423 braking resistor is produced by KEB within the BR Braking Resistors series. In a drive system, it converts surplus electrical energy from the DC link into heat, allowing frequency inverters on 400 V or 480 V mains to decelerate motors without overvoltage trips. The component is installed close to a converter as a dedicated energy-dissipation element in industrial automation lines. This arrangement helps control regenerative energy during rapid stopping, reversing, or downward-motion loads.
The resistor has a resistance of 42 Ω, which limits current flow at a given DC link level. It has a continuous dissipation rating of 100 W, which is the amount of heat the housing can release indefinitely when air flows freely around the fins. For heavy braking events, the unit tolerates a peak load of 14 kW, so short energy spikes are absorbed without reaching the thermal limit. These peaks are permissible as long as the cyclic duration factor remains at 2%, which keeps average heating within the continuous rating. The element may be connected to drive converters operating on mains voltages of 400/480 V, and it is insulated for a maximum DC link of 840 Vdc so the resistor stays below its dielectric limit. Power cabling can be landed on terminals sized for a conductor cross-section of 14 AWG / 2.5 mm², matching common machine wiring practices.
The resistor may be used in control cabinets where the surrounding air does not exceed 45 °C. During peak duty, its anodized casing may reach up to 125 °C without material degradation. Adequate spacing around the body helps heat leave the resistor more evenly during repeated deceleration cycles. Because only 2% of each cycle is occupied by high-energy braking, internal hot spots can cool between pulses and avoid cumulative thermal stress. A single mounting slot with a diameter of 12 mm accepts an M12 screw or stud, allowing the aluminum body to be fixed to a grounded metal panel for rapid heat transfer and vibration stability.
