2728180000

Overview

The Weidmüller 2728180000 is a split-core current transformer designed for industrial applications, specifically rated for a primary current of 3 kA and a secondary output of 5 A. It operates at 50 Hz and features a DIN rail mounting style. The device supports a maximum load of 15 VA with a tolerance class of 1. This component facilitates precise measurement of load current consumption using RMS value methods, accommodating asymmetrical cable feed-through for flexible installation in electrical distribution systems.

Feature Summary

• Split-core design allows for installation around existing cables without disconnecting the circuit
• DIN rail mounting style ensures secure attachment to standard industrial control panels
• Asymmetrical cable feed-through accommodates various cable configurations
• High accuracy tolerance class suitable for precise industrial current monitoring

Applications

• Industrial current consumption measurement
• Electrical distribution system monitoring
• RMS value method current sensing
• DIN rail mounted control panel integration

Procurement Notes

Verify that the required primary current rating matches the 3 kA specification and confirm the secondary output aligns with 5 A requirements. Ensure the operating frequency is compatible with 50 Hz systems. Check that the mounting environment supports DIN rail installation and that the connected load does not exceed the 15 VA limit. Confirm the tolerance class requirement meets the application's precision needs before finalizing procurement.

Selection Notes

Select this model when a split-core solution is necessary for retrofitting or non-intrusive current measurement in high-current industrial circuits. The 3 kA primary rating makes it suitable for heavy-duty applications where standard transformers may be insufficient. Consider the 5 A secondary output compatibility with downstream measuring devices. The DIN rail mount simplifies integration into existing switchgear or control cabinets without requiring additional bracketry.

Part Context

This part belongs to the KCMA series of split-core current transformers from Weidmüller. The specific designation KCMA-8-3000-5A-15VA1 indicates its core characteristics: 3000 A primary current, 5 A secondary output, and 15 VA burden capacity. It is categorized under industrial current transformers, distinct from metering or protection-only variants, offering a balance of accuracy and robustness for general industrial monitoring tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing, ensure the new component matches the 3 kA primary rating, 5 A secondary output, and DIN rail mounting style. Verify that any alternative split-core transformer maintains similar accuracy classes and burden capabilities to ensure system compatibility.
