AUTOMATIC CIRCUIT BREAKER Russian patent published in 2013 - IPC H01H73/00 

FIELD: electricity.

SUBSTANCE: automatic circuit breaker with thermal and electromagnet splitters, in which each pole is made of several (two or more) single-type low-ampere circuit breakers (1,2) controlled by a common handle (3), appropriate leads of which are connected in parallel with the help of connection elements (4,5), at the same time mechanisms of free disengagement of low-ampere circuit breakers are connected between each other with a disconnecting rack, on each connection element there is a clamp arranged for connection of external conductors (6,7) of appropriate cross section, and holes of screws in leads of low-ampere circuit breakers are closed with plugs (8-11), at the same time within each pole only one low-ampere circuit-breaker comprises thermal and electromagnet automatic splitters.

EFFECT: simplification of a device and reduction of its cost.
