CR5ASFT-751

Current Sense Transformers Overview

The CR5ASFT-751 is a current sense transformer manufactured by CR Magnetics Inc., designed for chassis mounting applications. It features a primary current rating of 750A and utilizes a split-core design to facilitate installation without disconnecting the main conductor. The device provides galvanic isolation between the high-current primary circuit and the secondary sensing circuit, ensuring safety and signal integrity in power monitoring systems.

Current Sense Transformers Feature Summary

• Split-core construction allows for non-intrusive installation on existing busbars or cables
• Provides galvanic isolation for safe current measurement in high-power environments
• Chassis mount configuration ensures stable mechanical positioning within electrical enclosures

Current Sense Transformers Applications

• High-current busbar monitoring in industrial power distribution panels
• Current sensing in variable frequency drives (VFDs) and motor controllers
• Power quality analysis equipment requiring isolated current feedback

Current Sense Transformers Procurement Notes

Verify the specific part number suffix against the manufacturer's latest datasheet to confirm mechanical dimensions and terminal configuration. Ensure the selected unit meets the required insulation voltage ratings for your application environment. Cross-reference the core type with the conductor size to guarantee proper fit and accurate measurement performance.

Current Sense Transformers Selection Notes

Select this component based on the 750A primary current requirement and the necessity for a split-core design during retrofitting or maintenance. Confirm that the chassis mounting style aligns with the available space in the control panel. Evaluate the secondary output characteristics to ensure compatibility with the connected measurement or protection circuitry.
