CR4410S-30

Current Sensors Overview

The CR4410S-30 is a single-phase average RMS AC current transducer from the CR4400 series, manufactured by CR Magnetics Inc. It features a split-core design with a 0.26-inch window and supports an input range of 0 to 30 AAC. The device provides a DC output signal proportional to the average RMS input AC current, available in 0-5 VDC, 0-10 VDC, or 4-20 mADC configurations. Key electrical specifications include a maximum supply current of 40mA, a response time of 250ms, and bidirectional polarization. Operating temperature ranges from 0°C to 60°C.

Current Sensors Feature Summary

• Split-core construction allows for easy installation around existing conductors without disconnecting the circuit.
• Produces a DC output signal directly proportional to the average RMS input AC current for accurate monitoring.
• Designed for multi-point current sensing applications with high accuracy and low cost.
• Interfaces with most commercially available instrumentation via standard voltage or current outputs.

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 (0-5 VDC, 0-10 VDC, or 4-20 mADC) required for your application, as this is not defined by the base model number alone. Confirm that the split-core variant (indicated by 'S') matches your conductor access needs. Ensure the operating environment stays within the specified 0°C to 60°C temperature range. Check for UL 61010B-1 recognition if safety compliance is mandatory for your installation.

Current Sensors Selection Notes

Select the CR4410S-30 when a split-core solution is needed for currents up to 30A RMS. Consider the physical dimensions of the 0.26-inch window to ensure it fits the target conductor size. Evaluate the system's need for bidirectional measurement capabilities. Compare against non-split core models if permanent wiring modifications are acceptable, potentially offering different form factors or cost structures.

Current Sensors Part Context

This component belongs to the CR4400 series of current transducers and transmitters. The series is designed to provide value packages for multi-point sensing. The 'S' suffix denotes the split-core design, distinguishing it from solid-core variants like the CR4410. The series includes various input ranges and output options to suit different instrumentation requirements.

Current Sensors Replacement Considerations

Direct substitutes may include other CR4410S models with different current ratings (e.g., CR4410S-5, CR4410S-10) if the 30A limit is not critical. Non-split core equivalents like the CR4410-30 exist but require different installation methods. Verify output signal compatibility before swapping between different series members.
