|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.
