General rules for choosing MCB a. Technical data of the network at the point considered: The earthing systems,short-circuit current at the circuit breaker installation point,which must always be less than the breaking capacity of this device,network normal voltage. b. There are 3 curvve characteristics for magnetic operation: B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems. C curve (5-10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current. D curve (10-14In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,breakdown lamps).
