Manufacturer of Residual Current Circuit Breakers with CE

Short Description:

CJRO2-40 Residual Current circuit breaker with overload protection (RCBO) ensure electrical safety in homes and similar situations, such as offices and other buildings as well as for industrial applications by protecting electrical installations against leakage Current reach to 30mA and against overloads and short circuits. Once a fault is detected, the RCBO automatically switches off the electrical circuit to prevent risk to the people and prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, RCBO are equipped with AC,A type. The AC type is a common type use for homes, A type with pulse DC protection, normally the rated current is 6,10,16,20,25,32A,leakage current protection is 30mA,100mA,300mA and rated voltage is 230VAC. frequency is 50/60Hz. according to IEC61009-1/EN61009-1 standards.

Overload Current Protection Characteristics

Test procedure Type Test Current Initial State Tripping or Non-tripping Time Limit Expected Result Remark
a B,C,D 1.13In cold t≥1h no tripping
b B,C,D 1.45In after test a t<1h tripping Current in the 5s in th increase of stability
c B,C,D 2.55In cold 1s<t<60s tripping
d B 3In cold t≤0.1s no tripping Turn on the auxiliary switch to close the current
C 5In
D 10In
e B 5In cold t<0.1s tripping Turn on the auxiliary switch to close the current
