4. The Over-Current Protection Property
MCB Selection
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.
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:
| Type | Tripping Current | Operating Time |
| Type B | 3 To 5 time full load current | 0.04 To 13 Sec |
| Type C | 5 To 10 times full load current | 0.04 To 5 Sec |
| Type D | 10 To 20 times full load current | 0.04 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.
