2420710000

Overview

The Weidmüller 2420710000 is a split-core current transformer designed for precise measurement of AC load current consumption using RMS value methods. It features an asymmetrical cable feed-through configuration, allowing installation without disconnecting the primary conductor. The device supports a primary current rating of 750 A and delivers a maximum secondary current of 5 A. It has a burden capacity of 5 VA and maintains a tolerance class of 1. This component is optimized for industrial panel monitoring applications requiring non-intrusive current sensing.

Feature Summary

• Split-core design enables installation around existing cables without circuit interruption
• Asymmetrical cable feed-through structure facilitates easy mounting on conductors
• Optimized for precise RMS-based current consumption measurement in industrial settings

Applications

• Industrial panel monitoring systems
• Precise measurement of AC load current consumption
• Non-intrusive current sensing in electrical distribution networks

Procurement Notes

Verify that the specific application requires a split-core topology rather than a solid-core alternative. Confirm that the primary conductor diameter fits within the asymmetrical feed-through aperture. Ensure the system burden does not exceed the 5 VA rating to maintain the specified tolerance class. Check for compatibility with downstream instrumentation accepting up to 5 A secondary current. Validate that the 750 A primary rating aligns with the maximum expected load current.

Selection Notes

Select this model when non-invasive installation is required for existing cabling. Choose based on the 750 A primary current requirement and 5 A secondary output capability. Consider the split-core form factor for retrofitting or temporary monitoring setups. Evaluate the 5 VA burden capacity against connected metering devices. Ensure the tolerance class 1 accuracy meets the precision requirements of the measurement application.

Part Context

This component belongs to the Weidmüller current transformer series, specifically engineered for industrial AC current sensing. It differs from fixed terminal blocks by providing galvanic isolation between primary and secondary circuits. The split-core architecture distinguishes it from solid-core transformers that require conductor termination. It serves as a sensor interface for energy monitoring and protection relays in electrical panels.
