I have a couple of issues with the simulation;
1. : the zener diode has Vz at 4.7V, it is not behaving as expected since it is reducing the supply voltage by 4.7 instead of setting it to that voltage.
2. : the SCR is not triggering and short circuiting the PSU.
3. : Is there a way to add a spice model to a thermal fuse in capture.
4. : Any recommendations on the values of the resistors and capacitor used?
