1.General

1.1 Application 

For protecting cables and equipment against overload and short circuit. 

1.2 General rules for choosing MCB 

a.Technical data of the network at the point considered.The earthing systems(TNS,TNC),Short-circuit current at the circuit-breaker installation point,which must always be less than the breaking capacity of thru device,betwork normal voltage. 

b.There are 2 curve characteristics for KBHB magnetic operation. 

B.Curve (3-5 In) protection and control of the circuits against overloads and short-circuits,protection for people and big 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.
