Using 600W load with C2 MCB
There is a simple formula that relates Volts, Watts and Amps.


  W = V * A


You know the watts and the volts, and need to know amps to compare that to your circuit breaker.  Basic algebra tells us that Amps is going to be Watts divided by Voltage.  So, your kettle is going to use


  600W / 220V = 2.7A (about 3 Amps)


A C2 breaker is rated for 2 Amps, so it would not be sufficient for that kettle.
