A modular residential circuit breaker comprises an assembly including an operation module and a first application module. The operation module includes an operation mechanism, a trip system, and an arc suppression system except a specific mounting and a current application. The first application module is configured to mate with the operation module to form a complete circuit breaker and define a replacement breaker frame for having an external modularity for the modular residential circuit breaker.

Modularity for circuit breakers

A smart residential circuit breaker includes a hybrid assembly that incorporates a solid-state circuit element integrated into a simplified mechanical pole having main contacts. The solid-state circuit element includes a printed circuit board (PCB) with a micro SD reader to provide faster opening speeds. The smart residential circuit breaker is configured for use for different current levels and controlled by the PCB. The smart residential circuit breaker includes a mag-latch. The PCB is configured to send a signal to the mag-latch to open and close the main contacts within microseconds of detecting an over-current.

Smart circuit breaker

An electrical contact is disclosed. The electrical contact includes a first element of a first material having one or more aperture, and a second element of a second material, the second element being positioned in at least one aperture of the one or more aperture of the first element, wherein the second material is different from the first material. Electrical contact devices, assemblies, and methods are provided, as are other aspects.

Electrical contact apparatus, assemblies, and methods

A lug arrangement for electrically connecting a conductor to a terminal of a circuit breaker. The lug arrangement includes a lug having a lug opening and first and second holes. The lug opening includes an opening for receiving the conductor and a slot for receiving the terminal. The lug arrangement includes a lug screw threadably engaged with the first hole for compressing the conductor against the terminal. Further, the lug arrangement includes a lug retainer for insertion into both the second hole and a third hole formed in the terminal. The lug retainer includes at least one protrusion that is moveable from a first position to a deflected position for enabling insertion of the lug retainer into the second hole. The at least one protrusion is also moveable back to the first position wherein the protrusion engages the second hole to attach the lug retainer to the lug.
