1.General
Application: For protecting cables and equipm-ents against overload and short circuit. General rules for choosing MCB. 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. There are 3 curve characteristics for magnetic operation:B curve (3-5 In) protection and control of the circuits against length cables in TN and IT systems. C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current. D curve (10-20 In) protection and control of the circuits against overloads and short-circuits; protection for circuits switch.
