Siemens 6SL3000-1BE31-3AA0 | S120 Braking Resistor 510-720V DC

Product Overview
The Siemens 6SL3000-1BE31-3AA0 is a braking resistor for the SINAMICS S120 drive system. This component is designed to dissipate regenerative energy from the DC link during braking operations .

When the DC link voltage rises to the activation threshold, the braking unit is enabled, connecting the braking resistor to the DC bus to convert regenerative energy into heat .
