The unique time delay feature of this fuse design helps solve the problem of nuisance “opening” by accommodating inrush currents that normally cause a fast-acting fuse to open. ## ~~**Features**~~ - Small size - Small size • UL Recognized to UL/ CSA/NMX UL 248-1 and - • Wide range of current rating available (0.375A UL/CSA/NMX UL 248-14 to 12A) **==> picture [494 x 92] intentionally omitted <==** **----- Start of picture text -----**
