| 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.
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.
