Overview
The Weidmüller 2728090000 is a split-core current transformer designed for non-invasive current measurement. It features a primary current rating of 250 A and a secondary current output of 5 A. The device operates at a frequency range of 50 Hz with a load capacity of 1.5 VA and maintains a tolerance class of 1. Measuring 155.00 mm in length and 22.83 mm in width, it utilizes a DIN rail mounting type for secure installation within control cabinets.
Feature Summary
- Non-invasive split-core design allows for easy installation around existing conductors without circuit interruption
- DIN rail mounting configuration ensures stable integration into standard industrial control panels
- Asymmetrical cable feed-through facilitates precise rms value-based current consumption monitoring
Applications
- Industrial automation systems requiring accurate current monitoring
- Electrical distribution panels for load management
- Energy efficiency analysis and power quality assessment
Procurement Notes
Verify the specific order number 2728090000 against manufacturer documentation to confirm compatibility with your system requirements. Ensure that the 250 A primary rating and 5 A secondary output align with your metering or protection devices. Confirm that the 1.5 VA burden capacity is sufficient for your connected load. Check for any regional certification requirements such as cULus if applicable to your market.
Selection Notes
Select this component when a non-invasive measurement solution is required for currents up to 250 A. The split-core architecture is ideal for retrofitting or modifying existing installations where conductor cutting is not feasible. Ensure the operating frequency matches your system's 50 Hz requirement. Verify that the DIN rail mounting space is available in your enclosure design.
Part Context
This current sense transformer belongs to Weidmüller's industrial sensor portfolio, focusing on reliable electrical measurement components. It complements their broader range of relay modules and terminal blocks by providing essential data acquisition capabilities for modern control architectures. The product supports the company's emphasis on durable and cost-effective infrastructure solutions.
Replacement Considerations
Consult official Weidmüller substitution guides for verified alternative part numbers. Do not assume cross-compatibility with other manufacturers' split-core transformers due to potential differences in burden capacity, accuracy class, or physical dimensions.
