Modular Power Distributor Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distributors are labor-intensive to mount and modify due to intricate wiring, and they are limited to single-pole or single-channel protective switches, requiring additional external connections for multichannel load circuits, increasing space requirements and connection effort.
Innovation Solution
A modular power distributor design featuring a supply module, signal module, and connection modules that can be easily mounted on a rail, allowing for direct connection of multichannel load circuits to a multichannel protective switch with reduced wiring effort, using a single connection module and enabling flexible configuration for single-channel or multichannel operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power distributors are used with individual wiring for each protective switch, then each load circuit can be individually protected, but the mounting becomes labor-intensive and the wiring becomes intricate
Solution Approach 1:
The power distributor is divided into multiple modular units, each housing one or more protective switches. Each module can be independently mounted on the rail and contains its own wiring infrastructure, eliminating the need for intricate external wiring while maintaining individual load circuit protection.
Solution Approach 2:
Multiple protective switches are combined within single modular units. The modules themselves are combined in series on the mounting rail, creating an integrated system where wiring is internalized within each module rather than externally connected between individual switches.
2Device complexity
If single-channel protective switches are used, then the system is simple to implement, but additional external terminals or potential distributors are required for multichannel load circuits, increasing space requirements and connection effort
Solution Approach 1:
The modular power distributor units are designed with universal applicability - each module can accommodate single-channel or multichannel protective switches depending on the application requirements. The standardized module design allows the same physical infrastructure to serve both single-pole and multi-pole configurations without requiring additional external terminals or potential distributors.

AI summary
A power distributor having a plurality of power distribution modules arranged in a row, for directly mounting on a carrier rail, having a supply module arranged on one end face and a signal module arranged on the opposite end face, and having at least one connection module arranged therebetween. The supply module has a supply connection for a main power line for tapping off a supply power. The connection module is fitted or can be fitted with a protective switch that can be actuated and a plurality of load connections for connecting to an interruptible load circuit by means of the protective switch. The signal module has a first signal connection for a switch signal actuating the protective switch, and the power distribution modules are or can be coupled to each other in an electrically conductive manner.
