Siemens 6SL3000-1BE32-5AA0 | S120 Braking Resistor for PM340

Product Overview
The Siemens 6SL3000-1BE32-5AA0 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. This helps control DC bus voltage when regenerative energy cannot be fed back to the grid .
