Siemens 6SE7021-8ES87-1FE0 Reactor

Siemens 6SE7021-8ES87-1FE0 is a line reactor designed for three-phase 380–460 V AC drive systems and intended for use with Siemens SINAMICS/Masterdrives equipment. The Type D enclosure measures 180 mm in height, 219 mm in width, and 99 mm in depth, and it weighs 8.0 kg, with mounting holes sized for M6 hardware. This 6SE7021 variant provides inductive impedance in the drive supply path to help manage transient loads and improve protection for connected drives in demanding industrial applications. Its compact form factor and the precise M6 mounting pattern support reliable installation alongside compatible Siemens drive components. When wiring and mounting, follow appropriate electrical safety practices and the manufacturer’s torque specifications to ensure proper fit and performance.
