Overview
The Weidmüller 2753070000 is a split-core current transformer designed for industrial applications. It features a primary current rating of 250 A and a secondary current output of 1 A. The device supports a maximum load of 1 VA with a tolerance class of 1. It utilizes an asymmetrical cable feed-through design for space-saving installation and enables precise measurement of connected load current consumption using RMS value methods.
Feature Summary
- Split-core construction allows for non-intrusive installation around existing conductors without disconnecting the circuit.
- Asymmetrical cable feed-through design provides a compact footprint suitable for space-constrained environments.
- Enables accurate determination of load current consumption through RMS value measurement techniques.
Applications
- Industrial electrical system monitoring
- Precise measurement of connected load current consumption
- Energy management systems requiring RMS value data
Procurement Notes
Verify that the required primary current does not exceed 250 A and the secondary burden remains within the 1 VA limit. Confirm compatibility with the specific cable diameter permitted by the asymmetrical feed-through design. Ensure the application requires a split-core configuration rather than a pass-through type to justify the mechanical interface.
Selection Notes
Select this component when non-invasive monitoring of high-current circuits up to 250 A is necessary. The 1 A secondary output is suitable for standard industrial meters or PLC inputs. Consider the physical dimensions of the asymmetrical opening against available installation space compared to symmetrical alternatives.
Part Context
This part belongs to the KCMA series of industrial current transformers from Weidmüller. The model number KCMA-28-250-1A-1VA-1 indicates its specific electrical ratings and mechanical form factor within the manufacturer's portfolio of measurement devices.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify exact dimensional and electrical compatibility before considering alternative manufacturers.
