Overview
The Weidmüller KCMA-42-400-5A-5VA-1 (Order No. 2753240000) is a split-core current transformer designed for industrial applications. It features a primary current rating of 400 A and a secondary current output of 5 A. The device supports a maximum load of 5 VA and maintains a tolerance class of 1. Constructed as a free-hanging module, it utilizes RMS value methods for precise measurement of load current consumption. The unit accommodates asymmetrical cable feed-through and complies with RoHS3 standards.
Feature Summary
- Split-core design enables installation without disconnecting the primary conductor
- Utilizes RMS value measurement methods for accurate current consumption monitoring
- Free-hanging mounting style facilitates flexible integration into electrical panels
Applications
- Industrial current monitoring systems
- Energy management and power distribution networks
- Electrical equipment requiring precise load measurement
Procurement Notes
Verify that the specific order number 2753240000 matches the required KCMA-42-400-5A-5VA-1 specifications. Confirm compliance with RoHS3 requirements and ensure the tolerance class 1 meets project accuracy standards. Check datasheet details for physical dimensions and assembly instructions to guarantee proper fit within the intended enclosure or panel layout.
Selection Notes
Select this component when a non-intrusive measurement solution is required for high-current circuits up to 400 A. The split-core architecture allows for retrofitting existing installations without power interruption. Ensure the connected burden does not exceed 5 VA to maintain the specified tolerance class. This model is suitable for environments where free-hanging installation is preferred over DIN-rail mounting.
Part Context
This part belongs to the KCMA series of industrial current transformers from Weidmüller. The series focuses on reliable signal conversion for automation and energy monitoring. The KCMA-42 variant specifically addresses applications requiring robust performance in industrial settings with standard 50 Hz frequency operation.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing wiring configurations before considering alternative models.
