Compact Fusible Disconnect Switch for High Density PDU Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fusible disconnect switch devices fail to meet the needs of high current industrial applications, particularly in data centers where higher power density and compatibility with standard rack-mounted power distribution units (PDUs) are required, and they are not easily compatible with face mounting installations.
Innovation Solution
The development of compact fusible disconnect devices with improved housing assemblies, terminal configurations, and ganging mechanisms that allow for increased power density, compatibility with standard rack-mounted PDUs, and face mounting capabilities, while maintaining voltage and current ratings of 600 VAC and 200 kA, and featuring a low-profile design for reduced size and enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If existing fusible disconnect switch devices are used, then basic circuit protection is provided, but power density is insufficient for high current industrial applications
Solution Approach 1:
The patent combines the fusible disconnect switch with the PDU mounting structure into an integrated assembly. The switch device is designed to be directly mounted within the PDU footprint, merging two previously separate components (fusible disconnect and PDU) into a single compact unit, thereby increasing power density without proportionally increasing overall device volume
Solution Approach 2:
The patent utilizes vertical stacking and three-dimensional space optimization within the PDU rack mounting structure. By arranging components in multiple dimensions rather than simple linear extension, the design achieves higher power density while maintaining compatibility with standard rack-mounted PDU form factors
2Volume of moving object
If compact design is implemented to increase power density, then device size is reduced, but compatibility with face mounting installations becomes difficult
Solution Approach 1:
The patent designs the fusible disconnect switch with universal mounting capabilities that accommodate both rack-mounted PDU installations and face mounting applications. The device includes standardized mounting interfaces and structural features that enable installation in multiple configurations, ensuring versatility across different installation environments while maintaining compact dimensions
Solution Approach 2:
The mounting structure is segmented into modular components that can be independently configured for different installation types. The device includes separate mounting brackets, attachment points, and structural elements that can be assembled in different arrangements to suit either rack-mounted or face mounting requirements

AI summary
A compact fusible disconnect switch device having a reduced switch housing size and increased power density is configured to be face mounted to a panel. A fuse cover assembly allows installation and removal of a fuse without having to open the panel. Line-side and load-side terminals are provided on a common side of the housing. In-line mechanical ganging and simultaneous application is provided for combinations of the compact fusible disconnect switch devices.
