CR4450-10

Current Sensors Overview

The CR4450-10 is a true RMS AC current transducer manufactured by CR Magnetics Inc. It features a two-element transformer design with a 0.26-inch window, supporting an input range of 0.5 to 30 AAC. The device provides a proportional DC output signal, available in 0-5 VDC, 0-10 VDC, or 4-20 mADC configurations. It operates on a 24 VDC power supply and delivers high accuracy for multi-point current sensing applications.

Current Sensors Feature Summary

• Two-element transformer construction for enhanced performance
• Proportional DC output signal corresponding to average RMS input AC current
• Available in multiple output formats including voltage and current signals
• Supports both DIN rail and panel mounting configurations

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, and 4-20 mADC options. Confirm that the 0.26-inch window accommodates the conductor size. Ensure the application requires AC current measurement compatible with the true RMS design. Check regulatory compliance requirements against UL 61010B-1 and IEC 61010-1 standards if necessary for the installation environment.

Current Sensors Selection Notes

Select this model when precise RMS measurement of AC current is required in industrial settings. The two-element design distinguishes it from single-element variants like the CR4410 series. Consider the physical window size constraint of 0.26 inches for conductor routing. Evaluate the need for bidirectional capability and the specific output signal type compatible with downstream instrumentation.

Current Sensors Part Context

The CR4450-10 belongs to the CR4400 series of current transducers and transmitters designed for value-oriented performance. This series includes single-element models such as the CR4410 and CR4420, which feature larger windows. The CR4450 series specifically targets applications requiring higher accuracy and two-element transformer technology within a compact module form factor suitable for standard industrial enclosures.

Current Sensors Replacement Considerations

For extended current ranges, utilize a 5 Amp secondary current transformer with the base unit. Split-core versions are available by appending 'S' to the prefix, such as CR4450S-10, for easier installation without breaking the circuit.
