CR4410-75

Current Sensors Overview

The CR4410-75 is a single-channel AC current transducer manufactured by CR Magnetics Inc. It utilizes an adjustable transformer design to measure alternating currents up to 75A. The device provides an RMS output signal, typically available in voltage or current formats such as 0-5VDC or 4-20mA, powered by a 24V supply. Key electrical specifications include a basic accuracy of ±0.5% and a frequency range of 50Hz to 400Hz. The unit features bidirectional sensing capabilities and a response time of approximately 250ms. It is designed for DIN rail or panel mounting within a module package.

Current Sensors Feature Summary

• Adjustable transformer technology for precise AC current measurement
• Bidirectional sensing capability for positive and negative current flow
• RMS output signal generation for accurate power system monitoring

Current Sensors Applications

• Industrial power distribution monitoring systems
• Electrical panel metering and protection circuits
• Energy management and load balancing applications

Current Sensors Procurement Notes

Verify the specific output configuration required, as the CR4410 series includes variants with different output types such as 0-5VDC, 0-10VDC, or 4-20mA. Confirm that the 75A primary rating matches the maximum expected load current. Ensure the operating environment falls within the specified temperature range and that the 24VDC power supply is stable. Check for RoHS compliance documentation if required by project standards.

Current Sensors Selection Notes

Select this model when high precision is required for AC current monitoring in industrial settings. The 75A rating suits medium-power applications. Consider the CR4410S variant if a specific secondary current output is needed instead of voltage. Verify compatibility with existing control system input ranges before procurement.

Current Sensors Part Context

This component belongs to the CR4410 series of AC current transducers from CR Magnetics. The series offers various primary current ratings, including 5A, 30A, and 75A options. These devices are designed for retrofitting into existing electrical panels to provide analog feedback for monitoring and control purposes.

Current Sensors Replacement Considerations

Direct substitutes may include other models from the CR4410 family with matching current ratings. Cross-reference output signal types carefully, as voltage and current outputs are not interchangeable without circuit modification.
