2. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   Normal fast-blow fuses are the most general purpose fuses. A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. These types of fuse are used on equipment such as motors, which can draw larger than ...

   The time delay of a No. 10 varies according to the concentration of the corrosive liquid in the vial. It is widely reported that the wire thickness varied also, but in fact all used the same diameter of wire. The time delay of a No. 9 is determined solely by the thickness of the notch in the wire, the spring tension, and the temperature.

5. ANSI device numbers - Wikipedia

   Device numbers may be combined if the device provides multiple functions, such as the Instantaneous / Time-delay Overcurrent relay denoted as 50/51. [ 3 ] For device 16, the suffix letters further define the device: the first suffix letter is 'S' for serial or 'E' for Ethernet.

6. Artillery fuze - Wikipedia

   en.wikipedia.org/wiki/Artillery_fuze

   Artillery Time fuzes detonate after a set period of time. Early time fuzes were igniferous (i.e. combustible) using a powder train. Clockwork mechanisms appeared at the beginning of the 20th century and electronic time fuzes appeared in the 1980s, soon after digital watches. Almost all artillery time fuzes are fitted to the nose of the shell.
