What is anti surge fuse?

The time delay fuse (also known as anti-surge, or slow-blow) are 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.

How do I know if I have an anti surge fuse?

The first letter(s) (TT, T, M, F, FF) tell you what type of fuse it is:

FF = Fast Fast. Very Quick Acting. ( also known as Anti Surge)
F = Fast. Quick Acting. ( also known as Anti Surge)
M = Medium. “Normal” or Very Short Delay.
T = Time. Time Delay or Slow Blow.
TT = Time Time. Long Time Delay or Very Slow Blow.

What is the purpose of fuse?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.

What does T on a fuse mean?

T = slow burn fuse. F = fast acting fuse. TT = very slow burn fuse. FF = very fast acting fuse.

Can you use a 250V fuse instead of 125V?

For example, a 125V fuse can be replaced with a 250V fuse of equal amplitude while the voltage of the application is 250V or lower, but a a 250V fuse can’t be replaced with a 125V fuse of equal amplitude if the voltage of the application exceeds 125V.

Can I replace a 3amp fuse with a 13amp?

Yes of course there is. The cable or flex attached to the gas fire is purely to supply the ignition. The flex provided is not rated to 13A because the ignition requires very little current and so the flex requires protection by a 3A fuse.

What happens if you use the wrong amp fuse?

Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill.
