CR4410S-20

Current Sensors Overview

The CR4410S-20 is a split-core AC current transducer from the CR4400 series by CR Magnetics Inc. It features a 20A input range and provides a proportional DC output signal corresponding to the average RMS input AC current. The device operates on a 24V supply with a maximum current consumption of 110mA. It supports bidirectional measurement and offers output options including 0-5V, 0-10V, or 4-20mA. The unit is designed for DIN rail or panel mounting and functions within a frequency range of 50Hz to 400Hz.

Current Sensors Feature Summary

• Split-core design allows installation without disconnecting primary conductors
• Produces a DC output signal proportional to average RMS AC input current
• Bidirectional sensing capability for accurate current direction monitoring
• High accuracy performance suitable for multi-point current sensing applications

Current Sensors Applications

• Motor fault monitoring systems
• Heating element monitoring
• Lighting element monitoring

Current Sensors Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required output types and input ranges. Confirm that the split-core variant meets mechanical window size requirements for the target conductor. Check regulatory compliance status against local safety standards such as UL 61010B-1 or IEC 61010-1 before integration into certified equipment designs.

Current Sensors Selection Notes

Select this model when non-intrusive installation is required due to its split-core architecture. Ensure the application involves AC currents within the 20A range and frequencies between 50Hz and 400Hz. Consider the available output signals (voltage or current) to match existing instrumentation interfaces. Verify power supply constraints align with the 24V requirement and 110mA maximum draw.

Current Sensors Part Context

This component belongs to the CR4400 series of average RMS AC current transducers. The series is engineered for value-oriented performance in industrial environments. The 'S' suffix denotes the split-core construction, distinguishing it from solid-core variants like the CR4410. These devices are designed to interface with commercially available instrumentation for precise current monitoring.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4400 series with matching input ranges and core types. Verify that alternative part numbers maintain the same split-core window dimensions and output signal specifications to ensure functional equivalence in existing setups.
