Product Description:
The 10.BR.100-6270 braking resistor from KEB belongs to the BR Braking Resistors series. It dissipates regenerated energy from inverter-driven motors as heat, protecting 400 V DC links from overvoltage during rapid deceleration. Mounted directly across the drive’s chopper output, the passive module lets automation equipment stop quickly without stressing power semiconductors.
The resistor has a continuous dissipation capacity of 130 W, meaning it can release this amount of thermal power indefinitely without exceeding its rated temperature rise. During fast stops, it can accept a short-term load of 2.1 kW for up to 6 s, with this interval limited by the internal thermal mass. Its element value of 270 Ω sets the braking current that flows when the inverter’s DC bus reaches the class limit of 400 V. The housing carries an IP60 rating, so dust ingress is prevented even though cooling air must still circulate through the fins. With a module count of 1 and no factory-installed connection terminals, wiring is completed with user-supplied leads. Concentrating heat in a single enclosure simplifies spacing inside compact cabinets.
Thermal supervision is provided by a normally closed temperature switch that opens at 160 °C. The contact can be routed to the drive’s enable circuit and is approved for switching up to 250 VAC/0.5 A; 30 VDC/0.5 A. The power leads fit a conductor size of 16 AWG / 1.5 mm², which provides a practical balance of ampacity and flexible routing through crowded cable ducts. Because the switch resets automatically after cooling, an NC contact helps prevent the drive from restarting until the resistor temperature drops to a safe value. Using external conductors compensates for the absence of factory terminals and maintains the clearance distances required by the IP60 enclosure.
