Product Introduction
1.Application:For protecting equipments against overload and short circuit.
2. 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 is 2 curve characteristics for magnetic operation:
B curve(3-5In)protection and control of the circuits against overloads and short-circuits;
C curve(5-10 In)protection and control ofthe circuits against overloads and short-circuits : protection for resistive and inductive loads with low inrush current.
