High Peak Power Rating 27 Ohm Resistance 380-480V Operating Range Designed for MICROMASTER 4 IP20 Protection Efficient Energy Dissipation

Product description

The Siemens 6SE6400-4BD21-2DA0 is a braking resistor designed for use with the MICROMASTER 4 series of variable frequency drives (VFDs). It has a resistance of 27 Ohms and can handle a peak power of 24000W, with a continuous power rating of 1200W. The resistor operates within a voltage range of 380-480V and has dimensions of 515x270x175 mm (HxWxD) with an IP20 protection rating.

This braking resistor is essential for applications where a drive needs to decelerate rapidly or dissipate excess energy generated during braking. It is commonly used in material handling, hoists, elevators, and other machinery with high inertia loads requiring controlled stops.

Stanlo Automation, a veteran-owned supplier of surplus industrial parts, offers the Siemens 6SE6400-4BD21-2DA0 braking resistor. Secure reliable automation components from Stanlo.
