CR4420S-100

Current Sensors Overview

The CR4420S-100 is a split-core average RMS AC current transducer designed for multi-point sensing. It features a 100A input range and provides a proportional DC output signal. The device supports bidirectional measurement with a 4mA to 20mA output option. Key specifications include ±0.5% accuracy, a 250ms response time, and operation within a 0°C to 60°C temperature range. It requires 24V power supply and consumes a maximum of 45mA. The module mounts on DIN rails or panels.

Current Sensors Feature Summary

• Split-core design allows installation without breaking the primary circuit
• Provides calibrated DC output proportional to average RMS AC current input
• Bidirectional sensing capability for accurate current direction detection

Current Sensors Applications

• Multi-point current sensing and control panels
• Motor fault monitoring
• Heating element monitoring
• Lighting element monitoring

Current Sensors Procurement Notes

Verify the specific output configuration required, as the series offers 0-5 VDC, 0-10 VDC, or 4-20 mADC options. Confirm the split-core variant suffix 'S' matches the application needs. Check regulatory compliance status against UL 61010B-1 and IEC 61010-1 requirements for your specific installation environment. Ensure the 24V power supply aligns with system constraints.

Current Sensors Selection Notes

Select this model when true RMS measurement of distorted waveforms is not strictly required, relying instead on average RMS conversion. Choose the split-core version for retrofitting existing busbars or cables where disconnection is impractical. Consider the 100A rating against peak load currents. Evaluate the 250ms response time against dynamic load changes. Compare against the CR4410S-100 if different output signals are preferred.

Current Sensors Part Context

Part of the CR4400 Series Average RMS Current Transducers. Designed for value-oriented industrial applications requiring high accuracy and easy integration with commercial instrumentation. The series includes single-element and two-element variants with various input ranges from 0.5A to 600A.

Current Sensors Replacement Considerations

CR4410S-100: Similar 100A split-core transducer; verify output signal compatibility (e.g., 4-20mA vs other options). CR4420S-75: Lower 75A rating; suitable only if load current remains below this threshold.
