Plug-in circuit breaker assembly

Abstract

A circuit breaker assembly includes a housing, an electrical bus structure coupled to the housing, and a number of first plug-in members coupled to the electrical bus structure. A number of circuit breakers include a first surface and a second plug-in member disposed opposite the first surface. The second plug-in member of each of the number of circuit breakers is mated with a corresponding one of the number of first plug-in members. A plate member is removably coupled to the housing. The plate member includes a first surface and an opposite second surface. The first surface of the number of circuit breakers engages the opposite second surface of the plate member in order to maintain mating of each of the number of circuit breakers with the corresponding one of the number of first plug-in members.

Description

technical field

[0001] The concepts disclosed herein relate generally to circuit breakers, and more particularly to circuit breaker assemblies, such as circuit breaker panels for many circuit breakers. Background technique

[0002] Circuit breakers are used, for example, in aircraft electrical systems not only to provide overcurrent protection but also as switches for switching devices on and off. Aircraft or subminiature circuit breakers, for example, are typically smaller to accommodate higher density layouts of aircraft circuit breaker panels that provide user access to circuit breakers for many circuits. An aircraft electrical system may, for example, consist of hundreds of circuit breakers, each for circuit protection functions and circuit disconnection functions by push-pull handles.

[0003] The push-pull handle of the circuit breaker moves from the inside to the outside to disconnect the corresponding load circuit. This action can be manual, or automatic in the eve...
