Mersen ATQR small-dimension fuse feature time-delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads. Mersen's ATQR fuse provide superior protection for the branch circuits of electrical distribution systems. Take control of fault currents headed for your control transformer. Fiberglass body provides dimensional stability in harsh industrial settings. High-grade silica filler ensures fast arc quenching and high current limitation. Applications: control transformers, solenoids, inductive loads, lighting, heating and generalpurpose loads. Approvals: UL listed to standard 248-4 File E2137, DC listed to UL standard 248, CSA certified to standard C22.2 No. 248.4.
