Abstract
A residual current operated circuit breaker is composed of the tripping device of the residual current operation circuit breaker and the circuit breaker. The circuit breaker is also equipped with a protective cover which is equipped with a plurality of big and small heat dissipating holes and a concave screw installation hole. The protective cover is installed on one side of the circuit breaker through screws. The heads of the screws are lower than the surface of the protective cover. The residual current operated circuit breaker is provided with good heat dissipation effect and improves the service life of products.
Description
Technical field
The utility model relates to a kind of residual current action breaker.
Background technology
Residual current action breaker (RCBO) has electromagnetic type electric current action type, voltage action type and transistor (integrated circuit) electric current action type etc.These residual current action breakers in use when particularly inner lead connects, more or less produce heat, because there is defective in their structure, cause radiating effect bad, directly influence the useful life of product.
The utility model content
The purpose of this utility model is to provide a kind of residual current action breaker, its good heat dissipation effect, the useful life of having improved product.
For achieving the above object, the solution that the utility model is taked is: a kind of residual current action breaker, it is made of residual current action breaker trip gear and circuit breaker, it also has protective cover, have several big and small louvres and a recessed screw mounting hole on this protective cover, by screw protective cover is installed in a side of circuit breaker, the head of screw is lower than the surface of protective cover.
Owing to the utlity model has the protective cover of band louvre, can leave in use the heat that produces when particularly inner lead connects.Its good heat dissipation effect, the useful life of having improved product.Because the head of screw is lower than the surface of protective cover, safety is attractive in appearance.
Description of drawings
Fig. 1 is the present embodiment stereogram.
Fig. 2 is the protective cover stereogram.
Among the figure: 1, circuit breaker, 2, the residual current action breaker trip gear, 3, protective cover, 4, louvre, 5, screw mounting hole, 6, screw.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of residual current action breaker, it is made of residual current action breaker trip gear 2 and circuit breaker 1, it also has protective cover 3, have several big and small louvres 4 and a recessed screw mounting hole 5 on this protective cover 3, by screw 6 protective cover 3 is installed in a side of circuit breaker 1, the head of screw 6 is lower than the surface of protective cover 3.
