Product Description:
The 14.BR.100-6853 braking resistor is produced by KEB within the BR Braking Resistors series. This component is installed on the DC link of a drive or inverter to convert excess regenerative energy into heat when a motor decelerates. By providing a controlled dissipation path, the resistor prevents DC-bus overvoltage and keeps the drive operating inside its specified limits in industrial automation lines such as conveyors, hoists, and test stands. As a passive energy sink, it contains an integrated thermal switch that reports overload conditions to the control system.
The resistor core is built from a single module, and its ceramic housing measures 28 mm thick and 80 mm high, allowing integration in narrow panels. Total body length is 400 mm, with 385 mm between mounting holes, so the assembly can sit flat against an enclosure wall while a 1005 mm silicone-insulated lead set reaches the terminal strip. A conductor cross section of 2.5 mm² minimizes voltage drop to the DC link. During repetitive braking sequences, the element can absorb 410 W continuously, provided that the duty cycle does not exceed 5 %. Heat is released through natural convection, and the enclosure has an IP60 rating, which keeps internal windings free from dust intrusion. These mechanical and thermal figures affect panel space, wiring gauge, and airflow requirements for machine builders.
In short bursts, the resistor tolerates 8.2 kW of peak dissipation, and this value is tied to the wire-wound element’s 85 Ω resistance and the drive’s DC-link voltage. It belongs to the 400 V class, so matching it to inverters with comparable link voltage limits current to safe levels. Overtemperature protection is handled by a normally closed switch that opens at 160 °C and can be wired to motor-control logic; its contacts carry up to 250 VAC at 0.5 A without additional relays. This switch helps protect the resistor during repeated high-inertia stops.
