Overview
The Weidmüller 2753420000 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 800 A and a secondary current output of 5 A. The device supports a maximum burden of 2.5 VA and maintains an accuracy tolerance class of 0.5. Operating at 50 Hz, this free-hanging in-line unit allows for asymmetrical cable feed-through, facilitating installation without disconnecting the primary conductor.
Feature Summary
- Split-core design enabling non-intrusive installation on existing cables
- Precise RMS-based current measurement capability
- Supports asymmetrical cable feed-through configurations
Applications
- Industrial current monitoring systems
- Energy management metering applications
- Load consumption measurement in electrical panels
Procurement Notes
Verify that the specific part number 2753420000 matches the required 800 A primary rating and 5 A secondary output before procurement. Confirm that the 2.5 VA burden capacity aligns with the connected measuring instrument's requirements. Ensure the physical dimensions accommodate the intended cable diameter for proper split-core closure.
Selection Notes
Select this component when high-accuracy RMS measurement is required for heavy industrial loads up to 800 A. The split-core architecture is essential for retrofitting or installations where breaking the primary circuit is not feasible. Consider the 0.5 tolerance class for applications demanding strict metrological standards in power distribution networks.
Part Context
This model belongs to the KCMA series of industrial current transformers from Weidmüller. It is engineered for robust performance in demanding electrical environments. The designation KCMA-8-800-5A-2.5VA-0.5 explicitly defines its core specifications, distinguishing it from other variants within the manufacturer's broader portfolio of sensing devices.
Replacement Considerations
Direct substitutes must match the 800 A primary rating, 5 A secondary output, and split-core form factor. Verify compatibility with existing mounting hardware and cable aperture sizes. Cross-reference technical datasheets to ensure equivalent accuracy classes and burden capabilities are maintained.
