SEFIE SF 30LE-32 1p+n C16 16A 30MA earth leakage circuit breaker elcb rccb rcd rcbo
1. provides protection against earth fault/leakage current,short-circuit,overload,and function of isolation.
2. Contact position indication
3. Provides protection against indirect contact by human body
4. Provides complementary protection against direct contact by human body.
5. Effectively protects electric equipment against insulating failure
| Test procedure | Type | Test current | Inital State | Tripping or Non-tripping Time Limit | Expected Result | Remark |
| a | B,C,D | 1.13In | cold | t≤1h | no tripping | |
| b | B,C,D | 1.45In | after test a | t＜1h | tripping | current in the 5s in the increase of stability |
| c | B,C,D | 2.55In | cold | 1s＜t＜60(In≤32A) | tripping | |
| d | B | 3In | cold | t≤0.1s | no tripping | turn on the auxiliary switch to close the current |
