6SE3290-0CA87-2RA0 SIEMENS

The 6SE3290-0CA87-2RA0 is a braking resistor meticulously engineered for Siemens Micromaster Vector Control (MMV) series drives, specifically models MMV12 through MMV75, including their /2 variants. This resistor effectively dissipates excess energy generated during braking, ensuring smooth and controlled deceleration of connected motors. It operates at a maximum DC voltage of 450V, providing robust protection against voltage spikes. The resistor is rated for a continuous power dissipation of 40W, suitable for sustained braking operations. It can also handle intermittent braking demands, with a peak power rating of 800W for up to 12 seconds at a 5% duty cycle. This intermittent capability allows for rapid deceleration in demanding applications. With a resistance value of 200 Ohms, it provides optimal braking torque while maintaining system stability. The braking resistor is crucial for preventing overvoltage faults and ensuring the reliable operation of the drive system. Its precise design and high-quality components contribute to efficient energy dissipation and extended service life. This component is essential for applications requiring frequent or rapid braking, such as elevators, cranes, and automated machinery.
