i'm having some difficulties with calculating the value of the thermal overload fuse in this circuit.
The thermal fuse is used to protect the motor and the circuit behind it. The deal problem is that the thermal overload fuse is in the live mains circtut and not after the AC-DC PSU.
And i cant seem to understand how to calculate the value. Could someone please help me understand what the formulas are and try to explain it to me? I have talked to other people and they say that its should be able to calculate the value.
I already have the thermal fuse for this its this module(Moeller PKZM0-0,25)
Supply voltage = 230VAC Motor nominal current 3A Motor Voltage 12VDC Adjustable Range of overload fuse = 160mA - 250 mA
