Abstract

A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

First claim

The invention claimed is:

1. A circuit breaker housing for holding a switching device and a number of connection contacts for a connection line and/or a busbar, the circuit breaker housing comprising:
a first housing part and a second housing part;
at least a first and second connection module having a connection contact for a connection line;
wherein, in a joined or assembled state, said first and second housing parts together form a front side and a rear side opposite said front side, and at least one connection side and end faces located opposite one another; and
wherein a holding chamber for receiving at least one connection module having one of said connection contacts is formed on said front side and/or on at least one of said connection sides; and
wherein each connection module has a module housing, which has a connection opening for a connection line, said connection opening leading to the connection contact, and a contact opening;
wherein the connection opening is arranged at that housing side of the module housing that faces toward the front side or the connection side, is flush therewith or forms same when the connection module is inserted into the holding chamber, and
wherein the contact opening is arranged at that housing side of the module housing that faces toward a chamber base of the holding chamber when the connection module is inserted into the holding chamber;
wherein the first connection module and/or the second connection module has a screw terminal or a screwless spring terminal as connection contact; and
wherein the connection contact of the first or the second connection module has a contact element for electrical connection with a coupling contact received by the housing parts in the joined or assembled state, the coupling contact being accessible via a housing slot provided on the connection side.

2. The circuit breaker housing according to claim 1 , wherein said housing slot extends over an entire housing width.

3. The circuit breaker housing according to claim 1 , wherein said holding chamber for said connection module is accessible from said front side and/or from the respective said connection sides.

4. The circuit breaker housing according to claim 1 , wherein said module housing is formed with a tool opening for actuating said connection contact, wherein said tool opening is arranged at that housing side of said module housing that faces toward said front side or said connection side, is flush therewith or forms same when said connection module is inserted into said holding chamber.

5. The circuit breaker housing according to claim 1 , wherein at least one of said first housing part or said second housing part is configured to hold a switch unit selected from the group consisting of mechanical, electrical or electronic, thermal, magnetic, and hydraulic switching devices.

6. The circuit breaker housing according to claim 1 , wherein at least one of said first housing part or said second housing part is configured to hold a switching device with a semiconductor switch or a contact system having a moving contact and a stationary contact.

7. A circuit breaker module, comprising a circuit breaker housing according to claim 1 , a switching device, and at least one connection module with a connection contact.

8. A circuit breaker, comprising: a plurality of single-pole or multipole circuit breaker modules, each of said circuit breaker modules including a circuit breaker housing according to claim 1 , a switching device in said housing, and at least one connection module with a connection contact.

9. The circuit breaker according to claim 8 , comprising a busbar configured to make plug contact with the coupling contact of the respective said connection module in order to jointly electrically conductively connect a plurality of connection modules and/or circuit breaker modules.
