I am a designer of a high power single phase 240 Vac lab equipment that could consume current 8-10 Amps during operating mode. I would recommend my client to use a power point that solely connected to a dedicated MCB to operate this equipment at his facilities. The power consumption would probably around 2 kW.
My client asked me which type of MCB should be allocated solely for this equipment? Here I told him:
Voltage Rating: 240Vac
Current Rating: 10A or above, preferrable 16A
Tripping curve: Type C
But how to determine correct breaking capacity of that miniature circuit breaker (MCB)? There is few options for breaking capacity: 4.5 kA, 6 kA, 10 kA, 15 kA and 25 kA. Which one I should go for?
Does the Prospective short circuit current of my lab equipment have something to do with this breaking capacity?
