Overload Current Protection Characteristics
| Test Procedure | Type | Test Current | Initial State | Tripping or Non-tripping Time Limit | Expected Result | Remark |
| a | B,C,D | 1.13LN | COLD | T≥1H | NO TRIPPING | |
| b | B,C,D | 1.45LN | AFTER TEST A | T<1H | TRIPPING | CURRENT IN THE SS INTHE INCREASE CF STATILTY |
| c | B,C,D | 2.55LN | COLD | 1S<T<60S | TRIPPING | |
| d | B | 3LN | COLD | T≥0.1S | NO TRIPPING | TURN ON THE AUXILIARY SWITCH TO CLOSE THE CURRENT |
| C | 5LN | |||||
| D | 10LN | |||||
| e | B | 5LN | COLD | T<0.1S | TRIPPING | TURN ON THE AUXILIARY SWITCH TO CLOSE THE CURRENT |
| C | 10LN | |||||
| D | 20LN | |||||
| THE TERMINOLOGY “COLD STATE” REFES TO THAT NO LOAD IS CARRIED BEFORE TESTING AT THE REFERENCE SETTING TEMPERATURE | ||||||
Residual Current Action Breaking Time
| Type | In/a | IΔn/a | Residual Current (IΔ) is Corresponding To The Following Breaking Time(S) | ||||
| AC TYPE | ANY VALUE | ANY VALUE | in | 2ln | 5ln | 5A.10A.20A.50A.100A.200A.500A | |
| ATYPE | ANY VALUE | >0.01 | 1.4ln | 2..8ln | 7ln | ||
| 0.3 | 0.15 | 0.04 | 0.04 | MAX BREAK-TIME | |||
| The general type rcbo whose current lΔn is 0.03ma or less can use 0.25A instead of 5 lΔn | |||||||
