The term "AT DR" on a fuse typically indicates that the fuse is an "A" type fuse designed for "Delay" or "Time-Delay" applications. This means it is built to withstand temporary overloads without blowing, allowing for brief surges in current, which is particularly useful in protecting motors and other inductive loads. The "DR" can also refer to specific ratings or characteristics defined by the manufacturer. Always consult the manufacturer's specifications for precise details.
