Modular Circuit Breaker with Interchangeable Detection Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contractors face the cumbersome task of maintaining and transporting a wide variety of circuit breakers with different interruption ratings and features to suit various applications, as existing solutions require a large inventory of specific circuit breakers for different load conditions and environments.
Innovation Solution
A field-configurable interruption apparatus comprising a first portion with a trip unit and a second portion with detection capabilities, both of which can be selected from various specifications and combined to form a customized apparatus suited to specific applications, allowing for modular assembly and connection to provide desired interruption ratings and fault detection features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide variety of circuit breakers with different interruption ratings and features are provided to suit various applications, then the adaptability to different load conditions and environments is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The circuit breaker is divided into separate functional modules: a base unit and interchangeable detection system modules. The detection system module can be selected and attached to match specific application requirements (ground fault detection, arc fault detection, or no detection), allowing contractors to carry fewer base units while achieving variety through module combinations.
Solution Approach 2:
The base unit is designed with universal compatibility to work with multiple types of detection system modules. A single base unit can be configured for different applications by attaching different detection modules, eliminating the need for multiple specialized circuit breaker models and reducing inventory complexity.
2Reliability
If multiple circuit breakers with specific detection capabilities are carried to meet various job requirements, then the ability to address specific detection needs is improved, but the loss of time for selecting and transporting the correct breaker increases
Solution Approach 1:
The detection system module can be dynamically attached or detached from the base unit depending on the specific job requirements. This dynamic configuration allows contractors to quickly adapt the same base unit for different detection needs by simply changing the module, rather than searching through multiple fixed configurations.
3Adaptability or versatility
If a comprehensive circuit breaker with all possible detection features is provided, then the adaptability to any application is improved, but the device complexity and cost increase
Solution Approach 1:
Detection features are segmented into separate interchangeable modules rather than being integrated into a single complex unit. This allows the system to provide comprehensive adaptability through module selection while keeping each individual module simple and manageable.

AI summary
An interruption apparatus includes a first portion having a trip unit and a second portion having a detection system. The first and second portions are individually selectable based upon the particular application and are then movable from a detached configuration to a connected configuration. The first and second portions are selected from a plurality of first portions and second portions having different specifications. A desired first portion having a first interruption rating and a desired second portion having detection capabilities that are suited to the particular application can be assembled together to provide a field-configurable interruption apparatus.
