Protect Input\Output port against short circuit ?

[Mayer_DEV]

Hello

I have a circuit that control on a 24VAC for a load
the problem is short circuit on those lines - my triac(8A) burnd
and I have fuse(5A) on my 24VAC source

How can I protect the line without using fuse\resettable fuse ?

The schematic -


Many thanks,

Mayer

Why not an auto- (thermally) resetting PTC fuse (also called: PolySwitch) for less than 1$ ?
