Abstract
Abstract A circuit breaker structure comprising a multipole circuit breaker having separable contacts for each pole, which circuit breaker is contained within an insulating housing; incoming and outgoing terminals extending from one wall of the housing which incoming terminals are aligned and reinforced against movement due to short circuits by a brace extending between and around the terminals on one side and a cap on the other side of the terminals for clampingly holding the aligned terminals in place.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
178 words
A circuit breaker structure comprising a multi-pole circuit breaker having separable contacts for each pole, an insulating housing for said circuit breaker and comprising front and rear end walls, each pole for said circuit breaker comprising at least two vertically spaced incoming and outgoing terminals extending from the rear end wall, the incoming terminals for all poles being horizontally spaced and aligned on one horizontal axis, the outgoing terminals for all poles being horizontally spaced and aligned on another horizontal axis and vertically spaced from that of the incoming terminals, terminal reinforcement means for supporting the terminals against movement in response to magnetic forces when a short circuit occurs, said means extending between and around the terminals on the outer side of the rear end wall, and the means comprising a separable brace and cap assembly which brace extends along one side of at least one of first aligned terminals, the cap extending along the other side of the first aligned terminals, and attachment means for securing the brace and cap into clamping engagement with the aligned terminals.
Claim 2
Dependent Claim
178 words
A circuit breaker structure comprising a multi-pole circuit breaker having separable contacts for each pole, an insulating housing for said circuit breaker and comprising front and rear end walls, each pole for said circuit breaker comprising at least two vertically spaced incoming and outgoing terminals extending from the rear end wall, the incoming terminals for all poles being horizontally spaced and aligned on one horizontal axis, the outgoing terminals for all poles being horizontally spaced and aligned on another horizontal axis and vertically spaced from that of the incoming terminals, terminal reinforcement means for supporting the terminals against movement in response to magnetic forces when a short circuit occurs, said means extending between and around the terminals on the outer side of the rear end wall, and the means comprising a separable brace and cap assembly which brace extends along one side of at least one of first aligned terminals, the cap extending along the other side of the first aligned terminals, and attachment means for securing the brace and cap into clamping engagement with the aligned terminals.
Claim 3
Dependent Claim
63 words
The circuit breaker structure of claim 1 in which the means comprises a second brace and cap assembly of which the brace extending along one side of second aligned terminals, a second cap extending along the other side of the second aligned terminals, and attachment means for securing the second brace and cap assembly together to clamp the second aligned terminals in place.
