Hi Andy ,Hi James,
Glad to hear you again!
Its a simple heater using for heat up the water(or oil),
Assembly inside boilers or water batch,
The circuits its very simple,, unfortunately i dont have i diagram, im sorry
Please consider it like a heater insiade the boiler,
Heater heat up the water to set-up temperature then switch off,
When water temperature drop down the heater start heating agian...
Im dont want to connect this heater into two phases,
Im just wonder what will happend if one phase will be disconnect,
Do you think that current will rise-up and will damage the heater?
Thanks a lot JamesHi Andy ,
For sure there will be current/load unbalancing in the case you described.
The thing is that this can make damage heater .
The case you are describing is like Overload operation and the associated protection ( thermal relay ) would trip in my opinion.
Ifthe power supply/protection relay... and wiring, are not sized correctly indeed then you can surely get some troubles, if you have one phase disconnected by any reason!
That what i can tell you from my own experience on power plant commissioning and other outages around the world .
Hope that this can help!
