Overview
The Weidmüller 2752990000 is a split-core current transformer designed for precise measurement of load current consumption using RMS value methods. It features a primary current rating of 100 A and a secondary current output of 1 A. The device supports a maximum burden load of 0.3 VA and maintains a tolerance class of 1. Constructed as an in-line unit, it accommodates asymmetrical cable feed-throughs, facilitating installation without disconnecting the primary circuit.
Feature Summary
- Split-core design enabling non-intrusive installation on existing cables
- Asymmetrical cable feed-through capability for versatile mounting
- RMS value measurement method for accurate current consumption monitoring
Applications
- Industrial current monitoring systems
- Energy management metering
- Load consumption analysis
Procurement Notes
Verify that the required primary current does not exceed 100 A and the connected burden remains within the 0.3 VA limit. Confirm compatibility with the specific cable geometry due to the asymmetrical feed-through design. Ensure the application requires a Class 1 tolerance level. Cross-reference the secondary current requirement of 1 A with the input specifications of the measuring instrument.
Selection Notes
Select this component when a split-core solution is necessary to avoid circuit interruption during installation. The 100 A primary rating suits moderate industrial loads. The 1 A secondary output must match the downstream device input. Verify that the physical dimensions accommodate the target cable diameter, considering the asymmetrical core structure.
Part Context
This part belongs to the KCMA series of industrial current transformers from Weidmüller. It is categorized under current sense transformers intended for precise electrical measurements. The model number KCMA-18-100-1A-0.3VA-1 encodes its key electrical specifications and form factor within the manufacturer's product line.
Replacement Considerations
Ensure any substitute matches the 100 A primary rating, 1 A secondary output, and 0.3 VA burden capacity. Verify the replacement also offers split-core construction and Class 1 accuracy. Physical compatibility with the existing cable assembly is critical due to the unique asymmetrical design.
