SFE20A

10PACK - 20Amp Continuous Current Rating, 32VAC Nominal Maximum Voltage Rating, 0.25" Diameter x 1.25" Length (Standard SFE-20 Size Dimensions), Glass-Body Fast-Acting Small-Dimension Automotive Cartridge Fuse. Utilizing a straight, high-conductivity zinc or copper alloy filament wire core positioned exactly at the center of a transparent glass cylindrical insulation tube, it is precision-calibrated to clear immediate short circuits and sustained overcurrent spikes instantly. This fast-acting electrical cutoff signature completely shunts high-energy line surges to protect legacy 12V/24V branch accessory lines, vehicle instrumentation loops, and mobile electronic communication modules from devastating localized thermal trace degradation. Equipped with high-conductivity nickel-plated brass end-cap terminals to ensure low contact resistance and an absolute phase-stable interface boundary directly across automotive distribution blocks, vintage electrical control panels, and marine electrical backplanes. Manufactured by Bussmann (Eaton). Exact part index: SFE-20 (also cataloged under bulk commercial index layout: SFE20A).
