Selection guide — worked example
Socket-outlet circuit in 2.5 mm², operational current 16 A, prospective short-circuit current at the board 4.5 kA. In = 16 A, curve C (general use); Icn 6 kA ≥ 4.5 kA. To break phase and neutral: TSB3-63 2P 16A, curve C. 3 kW water heater at 230 V: I = 3,000 / 230 = 13 A, hence a rated current of 16 A.
