Document Type and Number:
WIPO Patent Application WO/2008/022494
Kind Code:
A1
Abstract:
A leakage circuit breaker comprises a housing (I)5 a breaker tripping mechanism, a bimetal system, wherein characterized in that the leakage circuit breaker is comprised of a breaker tripping mechanism and a leakage tripping mechanism, wherein a lever A (10) of the breaker tripping mechanism is connected to a lever E (23) of the leakage tripping mechanism to form a double-deck tripping mechanism by connecting shaft; a bimetal system, wherein one end of the bimetal piece (15) is connected to one end of the bimetal link (14) to form L-shaped. The other end of the bimetal link (14) is connected to the latch A (6) of the breaker tripping mechanism. The tripping mechanism has a simple structure. The latch and the jumper are made of the same material, so they don't tend to deform. Conducting pieces (17) of the bimetal piece are connected to the wiring plate (19) by a flexible joint block (18), so the conducting pieces of the bimetal piece hardly move each other.
