Look for “Class G” printed on the fuse. These fuses can be recognized by either their round shaped bodies with or without blades. Look for the wording “One Time Fuse” printed on the fuse. These fuses can be recognized by a removable slotted end cap that can be removed so that the fuse material can be replaced.

What does the T mean on a fuse?

T. Slow Acting (Trage) TT. Very Slow Acting (Trage Trage)

What does 250V P mean on a fuse?

250V = Max working voltage. P = RoHS compliant (lead free)

How many amps is a 250V fuse?

Semiconductor Fuse – 250 Volts The 250 volt semiconductor fuse is a current limiting, very fast-acting, fuse rated to 250 volts AC and up to 250 volts DC. Current ratings range from 1 to 2,500 amps. The maximum interrupting rating, is 200,000 amps AC and 100,000 DC.

What does SFE stand for in fuses?

Special Purpose Fuse. Limiter – Fork Lift Fuse. In-Line Fuse. SFE Fuse.

How to identify f1al250v fuses?

Arrived in a plastic bag with no manufactured name. None of the fuses have a manufactured logo on the metal end caps as they should. Four of the fuses are marked as F1AL250V.

What is the difference between a 250V and a 5A fuse?

They are the same 5A 250V fast acting low breaking capacity fuses (just one omits the A of ampere) The time it takes for the fuse to open when a fault current occurs. It code could be: It is the current that a fuse is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.

What does F mean on a glass fuse?

In the glass fuses’ code F is for fast blown the second number is the current, but I ignore what is the difference between L an AL (if there is any).

What is a fuse fault current?

The time it takes for the fuse to open when a fault current occurs. It code could be: It is the current that a fuse is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.
