2420750000

Overview

The Weidmüller 2420750000 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 250 A and a maximum secondary current of 1 A. The device supports a load capacity of 4 VA with a tolerance class of 3. Operating at 50 Hz, it utilizes an asymmetrical cable feed-through design for free-hanging or in-line installation.

Feature Summary

• Split-core construction allows for non-intrusive installation around existing cables
• Asymmetrical cable feed-through design facilitates flexible mounting configurations
• Utilizes RMS value methods to ensure accurate measurement of current consumption

Applications

• Measurement of current consumption for connected loads
• Industrial equipment monitoring systems
• Electrical distribution panel integration

Procurement Notes

Verify the specific order code KCMA-18-250-1A-4VA-3 matches the required technical specifications. Confirm that the 250 A primary current and 1 A secondary output align with the system's measurement range. Ensure the 4 VA load capacity is sufficient for the connected metering or control devices. Check for compliance with relevant industrial standards applicable to the installation environment.

Selection Notes

Select this component when a split-core solution is required for retrofitting or modifying existing electrical circuits without disconnecting conductors. The 250 A primary rating suits high-current applications where direct insertion transformers are impractical. Consider the asymmetrical feed-through geometry if space constraints or specific cable routing requirements dictate a particular orientation during installation.

Part Context

This part belongs to the KCMA series of cable-type current transformers manufactured by Weidmüller. The series focuses on providing reliable connection solutions for device development and equipment manufacturing. As a commercialized product, it represents a standard offering within the manufacturer's portfolio for industrial current sensing applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 250 A primary current, 1 A secondary output, and 4 VA burden specifications. Verify compatibility with the existing asymmetrical cable feed-through requirement to maintain installation integrity.
