The BRU power resistor box assembles wirewound elements in an enclosure for inverter dynamic-braking circuits, test equipment, elevators and cranes.
The source lists an operating voltage below 800V, resistance from 1R-1kR, IP20 or IP23 construction and power options represented in the selection table. Choose the enclosure by braking power, duty cycle, resistance and matched braking-unit requirements.
