NBSe MB Series 2P Miniature Circuit Breaker,CB Certified


MCB Selection

1.The first characteristic is the overload which is intended to prevent the accidental overloading of the cable in a no fault situation. The speed of the MCB tripping will vary with the degree of the overload. This is usually achieved by the use of a thermal device in the MCB.

2. The second characteristic is the magnetic fault protection, which is intended to operate when the fault reaches a predetermined level and to trip the MCB within one tenth of a second. The level of this magnetic trip gives the MCB its type characteristic as follows:

·

TypeTripping CurrentOperating Time
Type B3 To 5 time full load current0.04 To 13 Sec
Type C5 To 10 times full load current0.04 To 5 Sec
Type D10 To 20 times full load current0.04 To 3 Sec

The third characteristic is the short circuit protection, which is intended to protect against heavy faults maybe in thousands of amps caused by short circuit faults.


The capability of the MCB to operate under these conditions gives its short circuit rating in Kilo amps (KA). In general for consumer units a 6KA fault level is adequate whereas for industrial boards 10KA fault capabilities or above may be required.


1. Application


The miniature circuit breaker mcb is mainly used in AC50/60Hz single pole220V or two,three,four pole 400V voltage for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit under nrmal condition.


The miniature circuit breaker mcb is suitable for industry, business, building, ressidence, etc.


The miniature circuit breaker mcb is conformity with GB10963,IEC60898 standards.
