CR4410S-100

Current Sensors Overview

The CR4410S-100 is a single-channel AC average RMS current transducer from the CR4400 series, manufactured by CR Magnetics Inc. It features a split-core design for non-intrusive installation and supports an input range of 0 to 100 AAC. The device operates on a 24V DC supply with a maximum current consumption of 30mA. It provides a proportional DC output signal compatible with standard instrumentation via RS485 interface. Key electrical specifications include a frequency response of 20Hz to 5kHz, an accuracy of ±0.5%, and a response time of 250ms. The unit is designed for bidirectional measurement and functions within an operating temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• Split-core transformer design enables easy installation without breaking the primary circuit
• Produces a DC output signal proportional to the average RMS input AC current
• Bidirectional sensing capability allows for accurate measurement in both directions
• Supports DIN rail or panel mounting configurations for flexible integration

Current Sensors Applications

• Multi-point current sensing and control panels
• Motor fault monitoring systems
• Heating element monitoring applications
• Lighting element monitoring circuits

Current Sensors Procurement Notes

Verify the specific suffix configuration when ordering, as the 'S' designation indicates a split-core variant which may differ functionally from solid-core models. Confirm that the required output interface matches the RS485 specification provided for this part number, as other variants in the series offer different output types. Ensure the application environment stays within the specified 0°C to 60°C operating temperature range to maintain the stated ±0.5% accuracy rating. Cross-reference the input current range requirements against the 100A limit to prevent sensor saturation.

Current Sensors Selection Notes

Select this model when a split-core solution is required for existing busbars or cables where disconnection is impractical. The 100A input range suits medium-power industrial loads. Consider the RS485 output if digital communication is preferred over analog signals. Verify that the 20Hz to 5kHz frequency range covers the operational spectrum of the monitored AC source. Compare against solid-core CR4410-100 if physical space constraints allow for direct conductor insertion rather than clamping around a cable.

Current Sensors Part Context

This component belongs to the CR4400 series of average RMS AC current transducers. The series is characterized by low-cost construction and high accuracy, designed to interface with most commercially available instrumentation. The CR4410S-100 specifically utilizes a single-element split-core architecture, distinguishing it from two-element designs or solid-core options within the same product family line.

Current Sensors Replacement Considerations

The CR4410-100 is a solid-core equivalent within the same series but lacks the split-core convenience. For split-core needs, verify compatibility with other CR44xxS variants based on the required amperage range. No direct cross-manufacturer substitutes are confirmed in public documentation; ensure mechanical window dimensions match the replacement sensor's core aperture.
