The Siemens 6SL3100-1BE31-0AA0 is a SINAMICS braking resistor rated for 600 V DC input with a continuous power dissipation of 1.5 kW and a peak (short-time) rating of 100 kW. This component is designed to absorb regenerative energy from a motor drive during deceleration or overhauling loads, converting it to heat rather than allowing DC-link overvoltage trips.
The lifecycle stage for this order code is listed as mature, meaning it is not in active new-production but remains available through independent distribution channels for BOM support and replacement needs. The datasheet carries a revision date of 07.01.2021 with the note "Änderungen vorbehalten" (subject to change without notice) © Copyright Siemens 2021, indicating the technical specification is frozen and no further design updates are expected.
The 1.5 kW continuous rating defines the resistor's steady-state heat dissipation capability — sized for the duty cycle of a typical SINAMICS drive braking application where the resistor sees repeated short-duration energy pulses rather than a constant load. The 100 kW peak rating is the instantaneous energy absorption capacity during a rapid deceleration event. Mounting and wiring should follow standard SINAMICS braking resistor practice: connect to the drive's DC bus terminals (typically DCP and DCN), with the resistor installed in a location that allows convective heat dissipation and does not expose adjacent components to excessive temperature rise.
