This utility model be the technical scheme is that
A kind of RCCB of big clearance for insulation, including housing, the first chamber for installing breaker unit it is provided with and for installing the second chamber of electric leakage unit in described housing, described breaker unit includes tripping mechanism, described electric leakage unit includes the second lever and wiring board, described second lever is provided with moving contact, also include dividing plate, described wiring board side is provided with the relief portion for dodging zero sequence current mutual inductor, opposite side is correspondingly arranged at above described moving contact, and described dividing plate is located between described moving contact and wiring board.
Described electric leakage unit also includes that magnetictrip, described magnetictrip are wholely set with described wiring board.
Described second chamber is additionally provided with the push pedal being correspondingly arranged with described magnetictrip, and described tripping mechanism also includes that snap close, described push rod are articulated with on described second lever and are linked with described snap close by second connecting rod in bottom.
It is correspondingly provided with static contact panel with described moving contact in described second chamber, also includes that arc-extinguish chamber, described arc-extinguish chamber are correspondingly arranged with described moving contact.
Described inner walls is also correspondingly provided with for the limited impression with described arc-extinguish chamber snap-fit engagement.
The beneficial effects of the utility model are: the RCCB of a kind of big clearance for insulation, the first chamber for installing breaker unit it is provided with and for installing the second chamber of electric leakage unit in its housing, breaker unit includes tripping mechanism, electric leakage unit includes the second lever and wiring board, second lever is provided with moving contact, wiring board side is provided with the relief portion for dodging zero sequence current mutual inductor, and opposite side is correspondingly arranged at above moving contact, and dividing plate is located between moving contact and wiring board.By being provided above dividing plate at moving contact, again wiring board is arranged on above dividing plate, then zero sequence current mutual inductor is arranged on the relief portion of the opposite side of wiring board, add the installing space of zero sequence current mutual inductor, reduce because zero sequence current mutual inductor is caused output parameter wild effect by external force extruding, add the insulation gap between circuit, decrease the risk being short-circuited.
