Abstract: A so-called blow-off type current limiting circuit breaker includes a stationary contact strap that is divided into three elongated closely spaced coplanar parallel arms that are connected to each other at one end of the strap. The stationary contact is mounted to the interior one of the parallel arms at the end thereof remote from the one end of the strap. A terminal portion of the strap connects exterior ones of the parallel arms to one another at the ends thereof remote from the one end of the strap. A movable contact engageable with and disengageable from the stationary contact is mounted to one end of a movable contact arm that is pivoted at its opposite end in the region of the one end of the strap, extending parallel to the arms of the strap and being aligned with the interior arm. Current in the interior arm flows in a direction opposite to the direction of current flow in the exterior arms and the movable contact arm. With the contact engaged, the interior arm and the movable contact arm are very close to one another so that upon the occurrence of severe fault current conditions, repelling electrodynamic forces of sufficient magnitude are developed between the movable contact arm and the interior arm to separate the contacts very rapidly, thereby limiting the magnitude of the fault current to a value within the rating of the circuit breaker.

Abstract: A magnetic trip means for automatically opening a circuit breaker contact upon the occurrence of predetermined fault current conditions is constructed of a stationary yoke, an armature biased away from the yoke and movable toward the yoke for tripping of the switch, an actuating coil in series with the contacts, and a sealed capsule coaxial with the coil for obtaining selected tripping characteristics. Within the sealed capsule there is a movable magnetic core biased to a normal position extending substantially outside the coil. The core is movable inside of the coil toward the armature upon the occurrence of overload current conditions with movements of the core toward the armature being retarded in a controlled manner. Control is obtained by closely spacing the outer cylindrical wall of the core and the inner cylindrical wall of the capsule, and additionally by utilizing a viscous fluid within the capsule. For a given overload current, as the core moves closer to the armature there is an increased force acting to move the armature toward tripping position.

Abstract: A so-called blow-off type current limiting circuit breaker is provided with an elongated movable contact arm that is pivotally mounted at one end thereof on a pin that projects from opposite sides of a support. The contact arm is constructed of parallel sections that are biased toward one another, by spring means disposed remote from the support, with the support being resiliently clamped between the sections to provide a good electrical connection between the support and contact arm. The pivot pin extends through aligned enlarged pivot apertures in the parallel sections to facilitate weld breaking. A wall of each pivot aperture is disposed to cooperate with the pivot pin to achieve a camming action that moves the contact arm slightly lengthwise after initial butting engagement of the circuit breaker main contacts to wipe the engaged contacts with respect to one another.

Abstract: A unitized combination starter is constructed with circuit breaker and contactor sections, each of which is provided with a pair of spaced stationary contacts and a cooperating movable bridging contact. The bridging contacts are closely spaced, are parallel and carry currents which flow in opposite directions. Under severe fault conditions a strong blowoff effect is created to force both bridging contacts in their respective contact opening directions. This quickly places four air gaps in the current path to severely limit current rise and thereby facilitate circuit interruption.
Abstract translation: 单元组合起动器由断路器和接触器部分构成，每个断路器和接触器部分均设置有一对间隔开的固定触头和一个可配合的可动桥接触头。 桥接触点紧密间隔开，平行并带有沿相反方向流动的电流。 在严重的故障条件下，产生强烈的吹除效应，以迫使桥接触头在它们各自的接触开口方向上。 这样可以快速地将四个气隙放置在电流路径中，严重限制电流上升，从而有助于电路中断。

Abstract: A switch has contacts constructed so that an electro-dynamic force is created by the current flowing through the switch which tends to maintain the switch in a closed state. This force counteracts other electro-dynamic forces which tend to open the switch. The contact design is particularly adapted from use in a single pole-double throw switch having a contact arm that is movable between two fixed contacts. The electro-dynamic force compensation exists between the contact arm and whichever one of the fixed contacts the contact arm is against. The fixed contacts also include arc runners so that any arc that develops as the contacts separate eliminates electro-dynamic force which tends to maintain the switch in a closed state.
