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.

Circuit breakers incorporating reset lockout mechanisms

A fault detector test device includes a test switch including a pivotable lever arm having a first end pivotably connected to rotate about an axis and a second end pivotable in an arc around the axis between an active position and an inactive position. A slide member has a first end accessible by an operator and a second end that cooperates with the second end of the lever arm, the slide member being slideable with respect to the axis of the lever arm such that the second end of the slide member slides in a plane that is substantially tangential to the arc in which the second end of the lever arm pivots. The second end of the slide member and the second end of the lever arm cooperate such that generally planar sliding motion of the slide member is translated into pivoting motion of the lever arm.

Circuit breaker with slide to test function

A circuit interrupter having a first plate on which a stationary contact is positioned where the flow of electrical current through the first contact and first plate cause a magnetic field to form around the stationary contact such that an arc that may form in the vicinity of the stationary contact is urged toward arc extinguishing plate and vented out the bottom of the housing of the circuit interrupter. In one configuration the venting is formed as a split vent path to direct the venting of gas and debris in a controlled manner.

Bottom venting circuit breaker

A circuit breaker includes a housing having a channel formed therein, the channel being defined by at least one side wall having a detent formed therein, a circuit breaker mechanism, a switch handle configured to toggle the circuit breaker, and an actuator module adapted to move the switch handle from the off position to the on position. The module includes a flexible portion having a protrusion formed thereon, the protrusion being sized, shaped and located to engage the detent when the module is mounted within the channel. The module also includes a locking clip moveable from an unlocked position, in which flexing of the at least one flexible portion is permitted, and a locked position, in which flexing of the at least one flexible portion is limited or prevented, such that when the module is mounted within the channel, removal of the module is inhibited.

A circuit interrupter including an arc extinguisher which functions to arrest an arc that develops between electrical contacts. The circuit interrupter includes a permanent magnet coupled at opposite ends to two magnetically permeable pole pieces that are configured to drive or urge an arc into toward an arc extinguisher. The device allows for arc motivation due to the magnetic field without requiring the use of electrical power and allows for a rugged, light-weight design.

Arc motivation device

A circuit interrupter having a compact design. According to some implementations, the circuit interrupter includes a conductor from a terminal to a contact having a portion that is angled with respect to the housing sides. This allows a fastener sleeve used to secure the device housing to be positioned closer to the center of mass of the housing, reducing the area of the housing. In some implementations, an arc splitter is provided which includes conductive plates that are angled with respect to the housing sides, allowing the area of the housing to be reduced. In some implementations, a terminal is designed to accommodate a connection without being doubled back, reducing the clearance required for the terminal and the overall area of the circuit interrupter.

Low-profile circuit breaker

A split housing circuit breaker having an auxiliary switch for connection to remote indicators that reflect the condition of the breaker has an actuator moveable between ON, OFF, and TRIPPED. When the actuator is moved between the ON and OFF positions, an auxiliary switch lever holds an auxiliary switch plunger against its bias to a normally-open condition for the auxiliary switch. When the actuator is in the TRIPPED position or reset to the OFF position after a fault, the plunger is allowed to extend and the auxiliary switch moves to the dosed condition. A trip lever sub-assembly includes an auxiliary switch lever that selectively acts on the plunger, a trip lever that selectively holds the auxiliary lever against the plunger, and a pin and torsion spring to rotatably interconnect the two said levers.

Reverse alarm switch circuit breaker

A circuit breaker bracket assembly has two generally U-shaped metal clips, each metal clip having a rearwardly projecting resilient wing formed therein with two forwardly projecting arms extending therefrom, each arm having an aperture which engages a nodule of a recess on a basal portion of a molded plastic cover plate. The molded plastic cover plate has a top face which has flanges preventing the cover plate from sliding through a panel opening. The basal portion has two mounting plugs formed on the back thereof which engage openings in each circuit breaker half case part and upon assembly of the circuit breaker holds the circuit breaker bracket assembly to the circuit breaker case.

Front mounting circuit breaker bracket assembly

A bracket assembly has rearwardly projecting metal wings mounted in a plastic cover plate. The circuit breaker is normally rear mounted in a panel. The cover plate is secured to the breaker with fasteners that secure the metal wings to the breaker housing. The metal wings have legs slidably received in the plastic cover plate providing a convenient subassembly for mounting the breaker from the front of a panel.
