The BK1/GMC-2-R is a 2A medium time-delay fuse in a 5x20mm glass tube package. It is rated for 250Vac and has an interrupting rating of 100A at 250Vac and 10,000A at 125Vac. Key electrical characteristics include a typical DC cold resistance of 0.043 Ω, a typical pre-arc I²t of 8.9 A²s, and a maximum voltage drop of 130 mV. Designed to UL/CSA 248-14 standards, this low breaking capacity fuse is ideal for consumer electronics and other applications requiring protection against sustained overcurrents.
