The Siemens 6SL3100-1BE31-0AA0 is a chassis-format braking resistor module designed for SINAMICS S120 drive systems, providing reliable energy dissipation during rapid deceleration and braking events. Operating within a 510–720 V DC range, this module safely converts regenerative energy into heat, protecting drive components and maintaining stable system performance. With a rated power of 1.5 kW and braking capability up to 100 kW, it is ideal for high-demand industrial motion applications.
This braking module is specifically engineered for SINAMICS S120 chassis systems, enabling direct installation in control cabinets without additional external hardware. It works in conjunction with Siemens braking choppers to manage excess DC bus energy generated during braking. This makes it an essential component in applications where frequent start-stop cycles or rapid deceleration occur, such as CNC machines, servo-driven automation, and high-speed production equipment.
Built for demanding environments, the 6SL3100-1BE31-0AA0 delivers consistent braking performance under heavy loads. Its air-cooled design supports continuous industrial operation while minimizing maintenance requirements. For facilities maintaining or extending the life of existing SINAMICS S120 systems, this module provides a dependable replacement option without requiring system redesign or upgrades.
Common applications include:
CNC machining centers
Servo and spindle drive systems
Robotics and motion control
Packaging and material handling equipment
Key benefits:
Efficient dissipation of regenerative braking energy
Protection against DC bus overvoltage
Chassis format for clean cabinet integration
Explicitly designed for SINAMICS S120 systems
Thoroughly tested and backed by MRO Electric
