CR4410S-40

Current Sensors Overview

The CR4410S-40 is a single-element, split-core AC current transducer from the CR4400 series by CR Magnetics Inc. It measures an input current range of 0 to 40A with a frequency response of 50Hz to 400Hz. The device provides a proportional DC output signal of 0V to 5VDC, representing the average RMS value of the input AC current. It operates on a 24VDC power supply (±10%) and features bidirectional sensing capability. The unit offers high accuracy with a ±0.5% error margin and includes conditioning circuitry for direct interface with standard instrumentation.

Current Sensors Feature Summary

• Split-core design allows installation without breaking the primary conductor
• Provides a DC voltage output proportional to the average RMS AC input current
• Bidirectional module supports measurement of current flow in both directions
• Integrated conditioning circuitry ensures compatibility with commercial instrumentation

Current Sensors Applications

• Multi-point current sensing systems
• Motor fault monitoring
• Heating element monitoring
• Lighting element monitoring

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range and output type. Confirm that the split-core window size accommodates the primary conductor diameter. Ensure the operating environment falls within the specified temperature and frequency ranges. Check for compliance with relevant safety standards such as UL 61010B-1 if required for the application.

Current Sensors Selection Notes

Select this model when a non-invasive current measurement solution is needed for AC currents up to 40A. The split-core configuration is ideal for retrofitting existing electrical panels or busbars. Consider the 0-5VDC output requirement against available PLC or data acquisition inputs. Verify that the 50Hz to 400Hz frequency range aligns with the system's operational spectrum.

Current Sensors Part Context

This component belongs to the CR4400 series of average RMS AC current transducers. The series is designed for multi-point sensing applications requiring reliable performance in control panels. The 'S' suffix indicates a split-core construction, distinguishing it from solid-core variants like the CR4410-40. These devices are engineered for DIN rail or panel mounting in industrial environments.

Current Sensors Replacement Considerations

The CR4410-40 serves as a solid-core alternative within the same series but requires conductor interruption for installation. Other models in the CR4410 family offer different input ranges, such as the CR4410S-10 for 10A or CR4410S-100 for 100A. Ensure the replacement maintains the split-core feature and matching output specifications.
