    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： In aspects of the present disclosure, a circuit interrupter includes a housing, a conductive path, a switch which selectively interrupts the conductive path, sensor(s), memory, and a controller within the housing. The sensor(s) measure electrical characteristic(s) of the conductive path. The memory stores an arc detection program that implements a machine learning model and includes a field-updatable program portion and a non-field-updatable program portion, where the field-updatable program portion includes program parameters used by the non-field-updatable program portion to decide between presence or absence of an arc fault. The controller executes the arc detection program to compute input data for the machine learning model based on the sensor measurements, decide between presence of an arc event or absence of an arc event based on the input data, and cause the switch to interrupt the conductive path when the decision indicates presence of an arc event.

    摘要： A circuit breaker and panel system includes a panel including a base pan having a plurality of base pan electrical connections. A circuit breaker including a housing having a plurality of circuit breaker electrical connections arranged to contact the base pan electrical connections when the circuit breaker is coupled to the base pan. The circuit breaker is rotatably coupleable with the base pan via a pivot joint for engaging the plurality of base pan electrical connections with the plurality of circuit breaker electrical connections per a predetermined electrical connection coupling sequence. One of the housing and the base pan includes a protrusion and the other of the housing and the base pan includes a corresponding recess which, when engaged with each other, retain the housing to the base pan to prevent reverse rotational movement of the breaker with respect to the base pan.

    摘要： An exemplary embodiment of a load control device with a light indicator is disclosed. The load control device may include an actuator assembly and a light source. The actuator assembly may include a frame, a light pipe, and an actuator having two surfaces. The light pipe may be arranged within the actuator and include first and second legs. The first leg may extend towards the first surface, and the second leg may extend towards the second surface. When the actuator is in a first position, the light source may be optically aligned with one of the first and second legs; and, when the actuator is in a second position, the light source may be optically aligned with the other of the first and second legs. When the light source is illuminated, the light pipe may direct the light towards the respective surface of the actuator.
