do external drives have short circuit protection?
However, as drives and soft-starters have grown smaller and smaller, the. internal fuses have been omitted by starter manufacturers in favor of short-. circuit testing to UL standards with external protection. Now, in many cases, drives are shipped without fuses, and it is the. responsibility of the installer or owner to provide this protection. During the. design and installation stages, it is important to check the data sheets, label, or manual of the power electronic device to understand the short-circuit. protection options.
