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 Amp-Trap 2000 ATQR fuses provide superior protection for the branch circuits of electrical distribution systems

  • Time-delay for control transformer inrush loads without nuisance opening

  • Highly current-limiting for low peak let-thru current

  • Rejection-style design prevents replacement errors (when used with recommended fuse blocks)

  • High-visibility orange label ensures instant recognition, and simplifies replacement

  • Metal embossed date and catalog number for traceability and lasting identification

  • Fiberglass body provides dimensional stability in harsh industrial settings

  • High-grade silica filler ensures fast arc quenching and high current-limitation
