High peak and continuous power ratings Designed for MICROMASTER 4 VFDs Effective energy dissipation Prevents VFD overvoltage IP20 protection

Product description

The Siemens 6SE6400-4BD22-2EA0 is a high-performance braking resistor designed for use with the MICROMASTER 4 series of variable frequency drives (VFDs). It is rated for 380-480V operation and has a resistance of 15 Ohms. This resistor can handle a peak power of 44000W and a continuous power of 2200W, dissipating excess energy generated during motor deceleration.

This braking resistor is crucial for applications where rapid or frequent motor braking is required, such as in cranes, hoists, elevators, and high-inertia loads. By providing a path for regenerative energy, it prevents overvoltage within the VFD, ensuring safe and reliable operation of the drive system. The resistor has a compact design with dimensions of 645 x 270 x 175 mm (H x W x D) and an IP20 protection rating.

Keep your MICROMASTER 4 drives protected with the Siemens 6SE6400-4BD22-2EA0 braking resistor, available from Stanlo Automation. As a veteran-owned surplus parts distributor, we offer genuine industrial components to support your automation needs, ensuring cost-effectiveness and quick turnaround.
