3A M205 Slow Blow Fuse

Sometimes referred to as a cartridge fuse, M205 fuses provide circuit protection in a huge range of devices. Sometimes marked with an S or T before the current rating (for example T3.15A), these delayed action fuses allow for a temporary current surge without going above the fuses current rating. Because of this, time delay fuses are most commonly used in applications where a large momentary load is expected such as motors at start-up.
