Siemens 6SE7023-2ES87-2DC0 Dynamic Braking Resistor

Description:

The Siemens 6SE7023-2ES87-2DC0 Braking Resistor is a dynamic braking resistor used with SINAMICS and SIMOVERT drive systems to dissipate regenerative energy during motor deceleration. Commonly installed in conveyor systems, cranes, hoists, elevators, machine tools, and industrial automation equipment requiring controlled braking and drive protection. Maintenance teams, OEMs, and system integrators use this braking resistor for replacement, retrofit, and preventive maintenance to ensure reliable drive performance and safe energy dissipation.

Applications:

The Siemens 6SE7023-2ES87-2DC0 Braking Resistor is used in variable frequency drive (VFD) systems, motor control applications, conveyors, cranes, hoists, winding machines, and automated production equipment. It safely absorbs regenerative energy generated during motor braking, reducing DC bus overvoltage and improving the reliability and stopping performance of industrial drive systems.
