ATQR Time-Delay Small-Dimension Fuses

Mersen ATQR Time-Delay Small-Dimension Fuses control transformer inrush loads without nuisance openings and offer high current-limiting for low peak let-thru currents. These fuses provide superior protection for the branch circuits of electrical distribution systems. The highly visible orange labels ensure instant brand recognition, simplifying replacement, and the fiberglass body provides dimensional stability in harsh industrial settings. Additionally, the high-grade silica filler ensures fast arc quenching and high current limitation. Mersen ATQR Time-Delay Small-Dimension Fuses are suitable for control transformers, solenoids, inductive loads, and lighting, heating, and general-purpose loads.
