CR7SFT-101

Overview

The CR7SFT-101 is a non-invasive solid core current sense transformer manufactured by CR Magnetics Inc. Designed for chassis mounting, this component features a primary current rating of 100 A and a secondary output ratio of 100:5. It operates within a frequency range of 50 Hz to 400 Hz, making it suitable for standard power line frequencies and higher harmonic applications. The unit utilizes a robust construction intended for reliable performance in industrial environments where accurate current monitoring is required without breaking the circuit.

Feature Summary

• Non-invasive solid core design allows for easy installation around existing conductors
• Chassis mount configuration provides secure mechanical stability
• Wide frequency operational range supports various AC power systems

Applications

• Industrial power monitoring systems
• Electrical panel current sensing
• Motor control circuit protection

Procurement Notes

Verify that the application requires a 100:5 current ratio and a 100 A primary rating. Confirm chassis mounting compatibility with the enclosure design. Ensure the operating frequency falls within the 50 Hz to 400 Hz specification. Check terminal type requirements against the datasheet specifications before ordering.

Selection Notes

Select this model when a non-invasive solution is preferred over split-core alternatives for permanent installations. Consider the 100 A rating to ensure the transformer does not saturate under normal load conditions. Evaluate the chassis mount style against available space constraints in the equipment housing compared to other mounting options.

Part Context

This component belongs to the CR Magnetics current sense transformer family, which offers various ratios and mounting styles. The SFT series typically denotes specific core materials and winding configurations optimized for accuracy. This particular part number represents a standard commercial grade option within their broader portfolio of magnetic components.

Replacement Considerations

Direct substitutes must match the 100:5 ratio, 100 A rating, and chassis mount form factor. Verify frequency response compatibility if used in high-frequency applications. Cross-reference terminal spacing and dimensions to ensure physical interchangeability in existing assemblies.
