Best competitive price economic type MCB miniature circuit breaker C45 series AC and DC model 63A
GENERAL
DZ47-63 (C45N)series high breaking capacity mini circuit breaker is used in AC50/60Hz, rated voltage of 230V 3, 4 poles 400V,
rated current to 63A for overload and short-circuit protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC60898 standard.It is economic type and best steady quality products.
1. Application:For protecting cables and 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 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.)
