Abstract
Abstract An automatic breaker, each pole of which comprises a movable and stationary system of contacts, characterized in that the stationary contact system is constituted as a series-wound coil having at least one turn and serving as an electrodynamic current limiter. The coil is composed of a stationary and movable element, the movable element of the coil serving as a stationary contact.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
An automatic breaker comprising movable contact means, and stationary contact means, said stationary contact means comprising a stationary member, and a movable member, said movable member and said stationary member each being substantially U-shaped, said movable member and said stationary member each including an end portion pivotally connected to one another about a fixed axis such that said movable member is pivotally displaceable about the fixed axis relative to said stationary member and to constitute said stationary contact means as a continuous series wound coil.
Claim 2
Dependent Claim
85 words
An automatic breaker comprising movable contact means, and stationary contact means, said stationary contact means comprising a stationary member, and a movable member, said movable member and said stationary member each being substantially U-shaped, said movable member and said stationary member each including an end portion pivotally connected to one another about a fixed axis such that said movable member is pivotally displaceable about the fixed axis relative to said stationary member and to constitute said stationary contact means as a continuous series wound coil.
Claim 3
Dependent Claim
30 words
An automatic breaker as claimed in claim 1, wherein the movable member of the series coil includes an elongated end portion constituting an arcing horn of the stationary contact means.
Claim 4
Dependent Claim
18 words
An automatic breaker as claimed in claim 1 including resilient means interposed between said movable and stationary members.
Claim 5
Dependent Claim
35 words
An automatic breaker as claimed in claim 1 including a contact element connected to said movable member, said movable contact means including a contact element adapted for contacting said contact element of said movable member.
Claim 6
Dependent Claim
33 words
An automatic breaker as claimed in claim 2 wherein said movable contact means includes an elongated end portion constituting an arcing horn for cooperation with said arcing horn of said stationary contact means.
Claim 7
Dependent Claim
29 words
An automatic breaker as claimed in claIm 1 including a lever connected to said movable contact means and adapted for permitting a manual displacement of said movable contact means.
Claim 8
Dependent Claim
24 words
An automatic breaker as claimed in claim 1 including arcing suppressor means and a flame-extinguishing grid connected proximate said movable and stationary contact means.
Claim 9
Dependent Claim
23 words
