ATQR small-dimension fuses feature time-delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads. Mersen’s ATQR fuses provide superior protection for the branch circuits of electrical distribution systems.

These ATQR Class CC time-delay fuses can handle transient surges without nuisance interruptions, making them particularly reliable in demanding industrial environments. The fiberglass body provides dimensional stability in harsh industrial settings, ensuring consistent performance even under extreme conditions.

The best choice for small transformer protection and current-limiting, ATQR fuses allow temporary inrush currents while reliably interrupting persistent overloads. They quickly reduce let-through energy during short circuits, protecting downstream components and minimizing equipment damage.
