Abstract
The invention relates to a molded case circuit breaker with a middle cover capable of being mounted with various parts, which is characterized by comprising a molded case circuit breaker base and a middle cover fixedly connected with the circuit breaker base, wherein the middle cover is provided with six circular holes for being fixed on the base, two grooves for the installation of auxiliary contacts, one groove for the installation of an alarm contact, one groove for the installation of an undervoltage tripper, one groove for the installation of a flux converter and one groove for the installation of a shunt tripper. The adoption of the middle cover capable of being mounted with various parts enables users to conveniently install and replace the parts.
Description
Technical field
The invention belongs to a kind of moulded case circuit breaker, particularly relate to a kind of mold cased circuit breaker that has the middle cover that multiple part can be installed.
Background technology
The lid overwhelming majority in the present known moulded case circuit breaker only possesses the function of lid, many parts all will be installed on the pedestal, fast development along with China's low-voltage distribution electrical equipment cause, the volume of moulded case circuit breaker is more and more littler, function is more and more, performance is more and more reliable, and the user uses more convenient.Therefore to covering the function that objective requirement not only will possess lid, also to increase other function.
Summary of the invention
The present invention provides a kind of function that not only possesses lid also to have the mold cased circuit breaker that has the middle cover that multiple part can be installed of other functions for solving the technical problem that exists in the known technology.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: it includes the moulded case circuit breaker pedestal and is connected in middle cover on the circuit breaker pedestal, and described middle cover has six and is used for fixing groove that circular hole on pedestal, two grooves that are used to install auxiliary contact, one be used to install Alarm contactor, groove that is used to install device for under-voltage releasing equipment, one and is used to install the groove of magnetic flow convertor, a groove that is used to install shunt release.
The present invention can also adopt following technical scheme:
Described two grooves that are used to install auxiliary contact are that rectangular trapezoidal groove, the described groove that is used to install Alarm contactor are that rectangular trapezoidal groove, the described groove that is used to install device for under-voltage releasing equipment are that square groove, the described groove that is used to install magnetic flow convertor are square groove, the described groove side of the being trapezoidal groove that is used to install shunt release.
Advantage and good effect that the present invention has are: owing to adopted the middle cover of multiple part can be installed, thereby make the user easy to install and replace.
