The OptiFuse MSC-P-315MA is a 315 mA medium time-lag glass fuse in the 5 x 20 mm size, with axial leads (pigtails), rated 250 VAC.
Medium time-lag sits between fast-acting and time-delay: it tolerates modest inrush while still clearing an overload quickly. The axial leads solder straight to a board or terminal strip, with no holder.
Breaking capacity: 10kA @ 125 VAC; 35 A @ 250 VAC; 100 A @ 250 VAC KC. Opening times, as a percentage of the rated current: 100%: min. 4 h; 135%: max. 1 h; 200%: max. 120 s. Typical melting I²t 0.2393 A²s. It operates from -55 to +90 °C.
Construction: glass body.
It is cULus Listed (UL file E197390). Standards: UL 248-14, CSA C22.2 No. 248.14.
