摘要： A molded case circuit breaker includes an interlock which prevents the operating handle from being placed in the off position after the main contacts have been welded together. By preventing the operating handle from being placed in an off position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.

摘要： An off-stop mechanism for a circuit breaker. Off-stop mechanism includes a handle moveable to an OFF configuration, the handle including a blocking engagement portion, a blocking member pivotally coupled at a pivot location, a linkage coupled between a cross bar housing and a linkage attachment location of the blocking member, the linkage being configured to: position the blocking member in an unblocked orientation when the main contacts are not fused together, and in a blocked orientation when the main contacts are fused together, wherein blocking member in the blocked orientation engages the blocking engagement portion as the operating handle is moved to the OFF configuration wherein the engagement places the blocking member in compression between the pivot location and the blocking contact portion. Circuit breakers including the off-stop mechanism and methods of operating a circuit breaker are also provided, as are other aspects.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing and rotatable between a contact open position and a contact closed position, and an operating mechanism disposed in the housing and interconnected with the contacts for rotating the contacts alternatively between the contact open position and the contact closed position. The operating mechanism includes a handle moveable by an operator between handle open and handle closed positions normally corresponding to and resulting in the contact open position and the contact closed position, with the handle including a protrusion. The operating mechanism further includes a crossbar assembly for rotating with the contacts as the contacts rotate between the contact open position and the contact closed position. The crossbar assembly includes a stop member that is positioned to abut against the protrusion as the handle is moved towards the handle open position when the contacts and the crossbar assembly remain in the contact closed position. The operating mechanism also includes a sideplate assembly having stops that prevent disengagement of the handle.

摘要： In the low-voltage circuit breaker that has a toggle lever system connecting the actuating arm to a carrier that moves the movable contact, a locking lever is provided to prevent transfer of the operating lever handle to its "off" position if the movable contact is welded to the stationary contact. The locking lever is pivoted about a bearing support formed in the housing of the circuit breaker. The opposite end of the locking lever is connected to the handle to be pivoted by it. The locking lever has an angled-off projection that extends into the path of movement of the carrier and is positioned to engage the carrier if the latter is unable to move from its "on" position due to welding of the contacts together. When the contacts are not welded together, the locking lever enforces the toggle levers to snap through to their "off" position before the angled-off part of the locking lever comes into contact with the carrier of the movable contact.
摘要翻译：在具有肘节杆系统的低压断路器中，该肘杆系统将致动臂连接到移动可动触点的支架上，如果可动触点是可动触点，则设置有锁定杆以防止操作杆手柄转移到其“关闭”位置焊接到固定触点。锁定杆围绕形成在断路器的壳体中的轴承支架枢转。锁定杆的相对端连接到手柄以由其枢转。锁定杆具有延伸到承载件的运动路径中的成角度的突出部，并且如果它们由于接触件的焊接而不能从其“接通”位置移动，则定位成与承载件接合。当触点未焊接在一起时，锁定杆在锁定杆的角度偏离部分与可动触头的支架接触之前，强制肘杆拉动到“关闭”位置。

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.
