180 Ohm Resistance 1000W Peak Power 50W Continuous Power For MICROMASTER 4 IP20 Rated Compact Dimensions

The Siemens 6SE6400-4BC05-0AA0 is a braking resistor designed for use with the MICROMASTER 4 series of variable frequency drives. It operates within a voltage range of 200-240V, has a resistance of 180 Ohms, and can handle a peak power of 1000W with a continuous power rating of 50W. The resistor measures 230x72x43.5 mm (HxWxD) and has an IP20 protection rating.

This braking resistor is crucial for applications where the motor needs to decelerate rapidly or where regenerative energy needs to be dissipated. It's commonly used in material handling, cranes, elevators, and other machinery with frequent stopping and starting cycles, helping to protect the VFD from overvoltage.

Stanlo Automation, a veteran-owned supplier of industrial automation parts, provides the Siemens 6SE6400-4BC05-0AA0 braking resistor. Secure reliable components for your VFD systems from our selection of surplus and new-old-stock inventory.
