02301.25ERT3SP 1.25A 230 Series 2AG Axial Fuse Littelfuse Slo-Blo

Littelfuse 02301.25ERT3SP uses a glass 2AG body and axial leads to deliver 1.25 A time-delay circuit protection. The published 230 Series data assigns this rating 16.8 A²s nominal melting I²t and 100 A @ 250 VAC; 10 kA @ 125 VAC/VDC; 80 A @ 310 VAC. The 0.25–1.25 A range is also documented for short-duration surge withstand in telecom equipment. This variant is supplied under a code representing reel-and-tape packaging, 2,500 pieces, T3=73 mm with S option; verify the required packaging before production release.
