CJRO2-40: Factory Direct Residual Current Circuit Breaker + Overcurrent Protection

Residual Current Circuit Breaker with Overcurrent Protection CJRO2-40

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
	C	10In
	D	20In
The terminology “cold state” refes to that no load is carried before testing at the reference setting temperature.
