NBBM-V460-A80

The ABB NBBM-V460-A80 Braking Chopper is a vital component for controlling motor deceleration and managing regenerative energy in industrial applications. Designed for use with ABB Low Voltage Drives, this braking chopper is engineered to operate reliably within a nominal AC line voltage range of 380-480V. Its robust construction supports a continuous load current of 115 A RMS, making it suitable for applications requiring significant braking torque. The minimum resistance rating of 2.19 OHM ensures effective dissipation of excess energy, preventing overvoltage conditions within the drive system. This unit, part of the NBBM series, is crucial for applications where rapid stopping or precise speed control is necessary, such as in material handling, cranes, elevators, and other machinery that frequently decelerates. By dissipating excess energy as heat through an external braking resistor (sold separately), the NBBM-V460-A80 protects the drive's DC bus capacitors and extends the lifespan of the drive components. Its integration is straightforward, allowing for efficient setup and operation within existing ABB drive ecosystems. The SKU NBBM-V460-A80 signifies a dependable solution for managing dynamic loads and ensuring operational safety and efficiency. When paired with appropriate braking resistors, this chopper provides a cost-effective method for handling braking energy, thereby improving overall system performance and reliability. Its specifications are tailored for industrial environments where consistent and predictable braking performance is paramount. The 115A current rating indicates its capacity to handle substantial braking power, while the 380-480V voltage compatibility aligns with common industrial power grids. The 2.19 OHM minimum resistance is a key parameter for selecting the correct braking resistor to match the chopper's capabilities and the application's braking requirements. This product is a testament to ABB's commitment to providing comprehensive drive solutions for a wide range of industrial needs, ensuring operational continuity and safety.
