Littelfuse FLA.250, Time Delay Midget Fuse With Indication, 1/4A, 125VAC, 1 Piece

The FLA series fuses are 125 V ac, pin-indicating, time-delay fuses for protection of control circuit transformers, solenoids, and other circuits with high in-rush currents. A metal indicator pin pops out 0.3" when the fuse opens, providing a visual indication of an open fuse. This built-in, blown-fuse indication quickly identifies which fuse or fuses within an electrical panel or system have blown. The time-delay design can carry an overload several times the normal load for a short period of time without blowing. FLA series fuses can be used in conjunction with special fuse blocks to operate mechanical signal switches or energize alarm circuits. Fuses rated at 12–30 amperes have dual-tube construction.
