Product Usage:
General rules for choosing MCB,For protecting cables and equipments against overload and short circuit.
a. Technical date of 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 curve characteristics for magnetic operation:
B curve (3-5 ln) protection and control of the circuits against length cables in TN and IT systems.
C curve (5-10 ln) protection and control of the circuits against overloads and short-circuits; protecton for resistive and inductive loads with low inrush current.
D curve (10-20 ln) 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)
