Claim 1
Independent Claim
60 words
A circuit breaker with an input side and an output side for connecting and disconnecting conductors in an electrical circuit, comprising: a magnetic breaker device which acts on a latching mechanism unit for opening a contacting device in case of overload, and an arc-quencher connected to said magnetic breaker device, wherein said magnetic breaker device includes two parallel connected coils.
Claim 2
Dependent Claim
60 words
A circuit breaker with an input side and an output side for connecting and disconnecting conductors in an electrical circuit, comprising: a magnetic breaker device which acts on a latching mechanism unit for opening a contacting device in case of overload, and an arc-quencher connected to said magnetic breaker device, wherein said magnetic breaker device includes two parallel connected coils.
Claim 3
Dependent Claim
34 words
The circuit breaker according to claim 1, wherein said latching mechanism unit includes two latching mechanisms which are respectively assigned to a contacting means, wherein each of said coils is connected to said arc-quencher.
Claim 4
Dependent Claim
26 words
The circuit breaker according to claim 1, wherein said input side and said output side are each provided with a stool clip for connecting said conductors.
Claim 5
Dependent Claim
19 words
The circuit breaker according to claim 1, wherein said latching mechanism unit comprises switch handles with a connecting handle.
Claim 6
Dependent Claim
126 words
A circuit breaker with an input side and an output side for connecting and disconnecting conductors in an electrical circuit, comprising: a magnetic breaker device which acts on a latching mechanism unit for opening a contacting device in case of overload, and an arc-quencher connected to said magnetic breaker device, wherein said magnetic breaker device includes two coils which are connected electrically in parallel between said input side and said output side, even when said circuit breaker is in a state where said conductors are disconnected, wherein a moveable plunger is disposed within each of said coils, and wherein said plunger is driven by a snap-action bimetal disk, said snap-action bimetal disk having a central through-bore for said plunger and being arranged outside said electrical circuit.
Claim 7
Dependent Claim
126 words
A circuit breaker with an input side and an output side for connecting and disconnecting conductors in an electrical circuit, comprising: a magnetic breaker device which acts on a latching mechanism unit for opening a contacting device in case of overload, and an arc-quencher connected to said magnetic breaker device, wherein said magnetic breaker device includes two coils which are connected electrically in parallel between said input side and said output side, even when said circuit breaker is in a state where said conductors are disconnected, wherein a moveable plunger is disposed within each of said coils, and wherein said plunger is driven by a snap-action bimetal disk, said snap-action bimetal disk having a central through-bore for said plunger and being arranged outside said electrical circuit.
Claim 8
Dependent Claim
23 words
