0230001ERT3SP 1A 230 Series 2AG Axial Fuse Littelfuse Slo-Blo

Littelfuse 0230001ERT3SP uses a glass 2AG body and axial leads to deliver 1 A time-delay circuit protection. Its electrical table gives 5.64 A²s nominal melting I²t, with interrupting ratings of 35 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. Its manufacturer order-code configuration is reel-and-tape packaging, 2,500 pieces, T3=73 mm with S option; use the datasheet when validating packaging and lead-form requirements.
