Overview
Littelfuse FLM 5A is a midget time-delay fuse rated for 5 amperes at 250V. Designed to protect control circuit transformers, solenoids, and other circuits with high in-rush currents, and also excellent for supplemental protection of small motors. The time-delay design can carry an overload several times the normal load for a short period of time without blowing. This makes it ideal for circuits where transient inrush currents are common.
Key Features
- Slo-Blo/Time Lag opening characteristic rated for 10,000A interrupting rating at 250VAC
- Non-indicating design, compatible with indicating fuse blocks for blown-fuse identification
- Midget (5AG) class package size with 125V DC rating in addition to 250V AC
- Compact cylindrical form factor fits standard 5AG fuse holders
- Non-indicating and may be used with an indicating fuse block to identify a blown fuse
