SIEMENS • 6SL3100-1AE31-0AB1
SINAMICS S120 Braking Module
Booksize braking module for controlled dissipation of regenerative DC-link energy.
01Product Overview
Siemens 6SL3100-1AE31-0AB1 is a varnished SINAMICS S120 booksize braking module for a 600 V DC link. It switches a connected external braking resistor when regenerative energy raises the DC-link voltage, providing a defined 1.5 kW rated braking capability and up to 100 kW peak output for two seconds.

04System Fit and Applications
Regenerative drive cyclesRoutes surplus DC-link energy to an external braking resistor during deceleration.
SINAMICS S120 booksize groupsIntegrates into compatible S120 line-ups using the specified busbars and clearances.
High peak braking demandSupports brief 100 kW braking events within the official two-second rating.
05Compatibility and Procurement Checks
- Match the complete order number 6SL3100-1AE31-0AB1 and the varnished-module construction.
- Verify the 600 V DC-link design, 770 V activation threshold and required braking-resistor rating.
- Check booksize mounting space against 50 × 380 × 270 mm dimensions.
- Confirm the external resistor cable route does not exceed 10 m and follows the SINAMICS engineering manual.
06Lifecycle Note
Siemens lists 6SL3100-1AE31-0AB1 as PM300: Active Product. Availability, delivery time and warranty scope should still be confirmed for the required quantity before order placement.
07Frequently Asked Questions
What is the peak output of 6SL3100-1AE31-0AB1?
The official data specifies 100 kW peak braking output for two seconds and 1.50 kW rated braking power.
Does the module include the braking resistor?
The module controls an external braking resistor; the resistor must be selected for the machine duty and DC-link design.
What DC-link range is specified?
The permissible DC-link range is 510 to 720 V DC, with a 770 V activation threshold.
What must be checked for replacement?
Confirm the exact order number, coated construction, booksize dimensions, busbar ratings and external resistor arrangement.
