摘要： Embodiments provide a circuit breaker exhibiting no trip at OFF functionality. The circuit breaker includes a blocking subassembly that effectively blocks tripping of a trip bar when the circuit breaker is in the OFF configuration. The blocking subassembly may include a translating plunger cooperating with a rotatable trip bar block. The trip bar block is aligned with the trip bar in the OFF configuration. Methods of operating the circuit breaker are provided, as are other aspects.

摘要： Multi-pole and single-pole circuit breakers include a housing and a reset lockout mechanism disposed within the housing. The reset lockout mechanism disables electrical communication between line and load terminals of the circuit breaker if a predefined condition exists. Some circuit breakers include a single actuator, transition between ON and OFF states, and are capable of performing test functions. The test functions may involve testing AFCI and/or GFCI functions of the circuit breakers. The test functions may be performed when the circuit breaker transitions from an OFF state to an ON state. Some circuit breakers including a reset lockout mechanism may be powered only on its line side. Some circuit breakers provide an electrical indication when they are in the OFF state.

摘要： A fusion welding isolation mechanism for an operating mechanism of a circuit breaker is provided. The operating mechanism of circuit breaker includes: a tripping component, a left side, a right side plate, a latch, a half shaft, a lever, and a main shaft. The tripping component, the latch, and the lever are mounted between the left side plate and the right side plate. The half shaft and the main shaft penetrate through the left side plate and the right side plate, and extend out of the left side plate and the right side plate. The tripping component, the latch, the half shaft, the lever, and the main shaft move in linkage. The lever and the main shaft are provided with isolation devices for preventing an operation handle from an opening operation when a moving contact is subject to fusion welding.

摘要： A solid state overload relay mechanism designed for minimizing the forces required to open an electrical contact associated therewith in the event of a current overload in a protected circuit, and further designed for overcoming residual magnetism in a solenoid initiating the opening of the contact. The contact includes a pair of stationary contacts supported by a base and a pair of movable contact supported by a contact carrier. A latch defines a notch which is normally engaged with a lever. When so engaged, the contact carrier is positioned such that the movable contacts are in contact with the stationary contacts. When the lever becomes disengaged from the latch, the contact carrier is moved and contact between the movable contacts and stationary contacts is broken. The latch is provided with a counterbalance weight to aid in minimizing the force required to return the latch to its original position after the mechanism is tripped. A latch arm extends away from the latch into the path of the lever such that as the lever travels to its extent in an arcuate path, the lever imparts motion on the latch to return it to its initial position, if such has not already occurred. An auxiliary stationary contact pair is supported by an auxiliary stationary contact housing and may be selectively installed in either a normally closed or a normally open position.
摘要翻译：一种固态过载继电器机构，其设计用于在受保护电路中的电流过载的情况下最小化打开与其相关联的电触点所需的力，并且进一步设计用于克服螺线管中产生触点开启的剩余磁性。触点包括由基座支撑的一对固定触点和由触点载体支撑的一对可动触头。闩锁限定了通常与杠杆接合的凹口。当接合时，接触载体被定位成使得可动触头与静触点接触。当杠杆从闩锁脱离时，触点支架移动，可动触头和固定触点之间的触点断开。闩锁设置有平衡重，以帮助最小化在机构跳闸之后将闩锁返回到其初始位置所需的力。闩锁臂从闩锁延伸到杠杆的路径中，使得当杠杆以弧形路径行进到其范围时，杠杆将闩锁运动以将其返回到其初始位置，如果还没有发生的话。辅助固定触头对由辅助固定触头壳体支撑，并可选择性地安装在常闭或常开位置。

摘要： A circuit breaker operating mechanism which may be set to constrain movable contacts to close with stationary contacts, but which is adapted to collapse resulting in the contacts opening. The operating mechanism comprises a toggle-link and a latch-frame articulated with one another so as to permit collapsing of the operating mechanism and a latch which may be disengaged to permit the collapsing. The invention provides in addition a latch-plate in the operating mechanism which by virtue of a lever advantage reduces the energy requirements to disengage the latch and so permits a more sensitive operating mechanism. The components are shaped to minimize space taken by the mechanism in its collapsed state.
