The OptiFuse FSA-P-25A is a 25 A fast-acting glass fuse in the 6.3 x 32 mm (1/4 x 1-1/4 in) size, with axial leads (pigtails), rated 32 VDC.
A fast-acting fuse opens quickly on an overload, for resistive and lightly loaded circuits with little switch-on surge. The axial leads solder straight to a board or terminal strip, with no holder.
Breaking capacity: 100 A @ 125 VAC (PSE); 100 A @ 250 VAC (PSE); 300 A @ 32 VAC/DC. Opening times, as a percentage of the rated current: 100%: min. 4 Hr; 135%: max. 1 Hr; 200%: max. 5 s. Typical cold resistance 0.0030 Ω, melting I²t 5902 A²s. It operates from -55 to +125 °C.
Construction: glass body.
It is cURus Recognized (UL file E197390). Standards: UL 248-14, CSA C22.2 No. 248.14.
