450V DC Operation 200W Continuous Power 4000W Peak Power 40 Ohms Resistance Designed for MMV Drives Overvoltage Protection

Product description

The Siemens 6SE3290-0CC87-2RA0 is a braking resistor designed for use with Siemens MMV series variable speed drives, including MMV220, MMV300, MMV220/2, and MMV400/2. It operates at 450V DC and provides a continuous power rating of 200W, with a peak rating of 4000W for short durations (12 seconds with a 5% duty cycle). The resistor has a resistance value of 40 Ohms.

This braking resistor is crucial for dissipating excess energy generated during motor deceleration in variable frequency drive systems. By connecting it to the drive's DC bus, it helps to protect the drive from overvoltage conditions and ensures smoother braking performance, extending the life of the drive and motor.
