2753290000

Overview

The Weidmüller 2753290000 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 1000 A and a nominal secondary current of 5 A, with a secondary apparent power capacity of 2.5 VA. The device operates at 50 Hz and carries a tolerance class of 0.5. It utilizes an asymmetrical cable feed-through design and supports free-hanging or in-line mounting styles. The unit has a height of 96 mm and is intended for commercialized industrial applications requiring accurate electrical monitoring.

Feature Summary

• Split-core construction allows installation without disconnecting the primary conductor
• Asymmetrical cable feed-through design facilitates specific routing configurations
• RMS value measurement method ensures accurate current consumption data
• Free-hanging mounting style provides flexible installation options

Applications

• Precise measurement of current consumption in connected loads
• Industrial electrical monitoring systems requiring RMS accuracy
• Energy management applications utilizing split-core sensor technology

Procurement Notes

Verify that the required primary current does not exceed 1000 A and the secondary burden remains within the 2.5 VA limit. Confirm compatibility with the 5 A secondary output specification for downstream instrumentation. Ensure the physical dimensions, specifically the 96 mm height, fit the designated mounting space. Check for any specific environmental ratings if the installation location presents unique operational challenges.

Selection Notes

Select this component when a split-core solution is necessary to measure currents up to 1000 A without breaking the circuit. The 5 A secondary output is suitable for standard ammeters or data acquisition systems. Consider the asymmetrical feed-through requirement during cable planning. This model is appropriate for applications where non-intrusive installation and high accuracy (Class 0.5) are prioritized over compact form factors.

Part Context

This part belongs to the KCMA series of current transformers from Weidmüller. The full designation KCMA-42-1000-5A-2.5VA-0.5 indicates the series, primary current, secondary current, burden, and accuracy class. It is distinct from solid-core variants and other current sensing technologies like Hall effect sensors, focusing specifically on magnetic induction for AC measurements.
