High Power VFD Brake Resistor 5KW 10KW 15KW 20KW 10R 20R 50R AC 380V Load Heavy Duty Braking Resistor Box

Description

The RESBX brake resistor box is designed to work with frequency inverters to safely dissipate excess regenerative energy generated during motor deceleration. When the motor slows down, the inverter converts the surplus kinetic energy into electrical energy. The brake resistor box absorbs this energy and releases it as heat, preventing over-voltage on the DC bus and ensuring stable operation of the inverter system.

Built with high-quality wire-wound or metal-clad power resistors, the resistor box provides high thermal stability, strong overload capability, and excellent durability. The enclosure is typically made of ventilation-optimized metal housing to improve heat dissipation and enhance safety. This solution is widely used in lifting equipment, cranes, conveyor systems, CNC machines, elevators, and other applications requiring frequent start/stop or rapid braking.
