Product description

The Siemens 6SE3290-0CA87-2RA0 is a braking resistor designed for use with Siemens MMV drives (MMV12-MMV75 and MMV12/2 - MMV75/2). It is rated for 450V DC and has a continuous power rating of 40W, with a peak rating of 800W for short durations (up to 12 seconds, 5% duty cycle). The resistor value is 200 Ohms.

This braking resistor is essential for dissipating excess energy generated during deceleration of motor loads, particularly in applications where dynamic braking is required. It helps to protect the drive system by limiting the DC bus voltage, ensuring safe and controlled motor operation in variable speed drives.

Source your Siemens 6SE3290-0CA87-2RA0 braking resistor from Stanlo Automation, a veteran-owned surplus parts distributor, to ensure your variable speed drive systems are equipped with reliable components.
