Hi there,
Can I know the part numbers for the following pls?
Fuse Slow Blow (200mA)
Thermal Fuse (72ºC)
Fuse Quick Blow (630mA)
Varistor

2023 now, isn’t there a safe, simple and compact solution yet?

In reply to Sara Santos. Why not? I actually wanted to give it a try, but I'm too lazy to develop a pcb

What if I use LVR200 240V 2A Tyco Raychem PPTC Resettable Fuse instead of 72°C thermal fuse?

In reply to Vin. Sorry forgot to mention its 240V 630mA slow blow fuse 14D241K varistor and HLK-5M05

Hi I got this setup but the varistor and fuse keep blowing and cant figure out why, i created my own pcb, as per the circuit diagram

Hi.
Yes, but we ended up not building the PCB.

Nice! Was there enough interest to develop a pcb?

In reply to Sune. Its to do with the reactance ( resistance) at various frequencies.
