Meba mcb MB17

Meba mcb MB17 adopts advanced design technology, it has protective function as shortage as overload, and are used in lighting distribution system industry, commerce and dwelling, and protecting fractional electric motors, and they also have many merits of high protective grade(up to IP20), high breaking capacity, reliable sensitive action, convenient, multiple assembling, long life etc. Meba mcb MB17 are mainly adapted to the circuit of AC 50Hz, 230V in single pole; 400V in double, three, four poles for protecting overload and short circuit, meanwhile Meba mcb MB17  are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.

Meba mcb MB17

Technical parameters:

1.For protecting cables and equipments against overload and short circuit.

2.General rules for choosing MCB.

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 2 curve characteristic 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.
