Siemens 450V Braking Resistor for MMV Drives - 80W Continuous

The Siemens 6SE3290-0CB87-2RA0 is a braking resistor designed for use with Siemens MMV110, MMV150, MMV110/2, and MMV150/2 drives. It has a DC voltage rating of 450V, a continuous power rating of 80W, and a peak power rating of 1600W for 12 seconds with a 5% duty cycle. The resistance value is 100 Ohms.

This braking resistor is essential for dissipating excess energy generated during regenerative braking in variable speed drives, preventing overvoltage and ensuring safe operation. It is commonly used in applications with frequent stopping or overhauling loads, such as cranes, hoists, elevators, and high-inertia machinery.
