Product Description:
The KEB BR Braking Resistors, Model 09.09.870-744U, offer improved VFD performance for braking functions in a variety of industrial applications.
The resistor is available in the two classes of 230V and 400V, suitable for various power systems. The resistor can withstand up to 26kW continuously and up to 440kW for a short time (6 seconds maximum) duty worth handling load energy during the braking process. IP20 protection is standard, with an IP60 option for increased protection against dust and moisture providing an additional layer of durability and reliability in harsh environments. The 09.09.870-744U is certified with CE and UL marks and, therefore, it complies with international safety and quality norms and can be used in any part of the world. With flexible mounting options, these are provided as universal side-mounted units or bus-mounted modules to meet the needs of different types of installation. It offers a variety of core cross-section options like 14 AWG / 2.5 mm² depending on required electrical properties. BR series resistance values vary between 10 to 390 ohms to support different operating conditions.
Dimensions of the physical aspects differ according to the model in question, with one approximately equal to 240 mm x 26 mm x 225 mm. The connection terminals are designed with wire sizes of 14 AWG (2.5 mm²) to 16 AWG (1.5 mm²), for easy interfacing with existing systems. These special braking resistors are designed to match with KEB COMBIVERT frequency inverters for the best braking performance overall. It also incorporates built-in thermal switches which activate at particular temperatures thereby preventing overheating during operational temperatures of -10 to +45 C. It can be purchased at Wake Industrial with a one-year warranty.
