Extension board fuse usage?

[Biojardim]

Hi,
Today i needed to repair an extension board, bcs the solenoid (short Circuit) died and burned one triac.
My question, is possible to use an fuse on each prot so i can prevent this type of damage?

I noticed the triacs are 600 mA for 600 volts, so can i use an 500 mA /250 V with socket?

If no, what is the recomended tension and current for the fuse?

Thanks,

There is a fuse in line with the COM wire. If you want to protect each individual valve line, you can add additional fuse in line from each station port to the station wire. 500 mA /250 V fuse should be fine but is a bit low on the amperage. Each valve draws about 400 to 500mA impulse current and 250 to 350mA holding current.
