Circuit Breaker Mounting Bracket with Rear Hook Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and removal of circuit breaker units require manual support due to the need for precise positioning of electrical connections and mechanical weight-supporting connections, which can be labor-intensive, especially for heavier units, and are limited by existing electrical components in enclosures.
Innovation Solution
A mounting system with a bracketry that includes spacer and hook portions to support the weight of the circuit breaker unit, allowing for secure fastening to mounting rails without requiring additional manual support, even in enclosures with pre-installed components, enabling easier installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual positioning is used to accommodate electrical connection geometry, then precise positioning is achieved, but manual labor intensity increases
Solution Approach 1:
The circuit breaker unit is pre-positioned on the mounting rail before electrical connections are made. The mounting rail provides a predetermined positioning structure that guides the breaker into the correct position, eliminating the need for manual positioning during installation while maintaining precision.
Solution Approach 2:
The mounting rail acts as an intermediary component between the circuit breaker unit and the mounting surface. It provides both mechanical support and precise positioning, allowing the breaker to be easily installed without requiring manual alignment while ensuring accurate geometric positioning for electrical connections.
2Reliability
If manual weight support is required during installation, then secure mounting is achieved, but labor effort increases
Solution Approach 1:
The mounting rail is pre-installed on the mounting surface with engagement structures that automatically support the weight of the circuit breaker unit when it is placed on the rail. This preliminary preparation eliminates the need for installers to manually support the breaker weight during installation, while ensuring secure mounting through the predetermined engagement structures.
3Reliability
If existing electrical components are present in the enclosure, then electrical functionality is maintained, but installation space is reduced
Solution Approach 1:
The mounting rail extends into the depth dimension of the enclosure, utilizing the third dimension (depth) to provide mounting space. This allows circuit breaker units to be mounted on the rail in a manner that accommodates existing electrical components in the horizontal plane, effectively adding installation capacity in the depth direction without interfering with existing components.

AI summary
An apparatus includes a circuit breaker and mounting bracketry fastened to the rear side of the circuit breaker. The mounting bracketry includes first and second spacer portions extending rearward from a respective locations inside the width of the circuit breaker unit, first and second fixation portions extending outward from the first and second spacer portions, respectively, to respective positions outside the width of the circuit breaker, and first and second hook portions extending rearward from the first and second fixation portions, respectively. The circuit breaker may be mounted to an electrical enclosure with the first hook portion and the second hook portion engaging a mounting rail of the electrical enclosure.
