CR7SFT-801

Overview

The CR7SFT-801 is a commercial grade AC current transformer manufactured by CR Magnetics Inc. It features a solid core design with an 800 AAC input range and a 5 AAC output range, providing an 800:5 current ratio. The device operates within a frequency range of 50Hz to 400Hz and utilizes a mounting case with two #8-32 terminals for connection. It has a 2.5-inch inner diameter and is designed for chassis mounting applications.

Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• Commercial grade classification suitable for general monitoring
• Chassis mount configuration with standard terminal connections

Applications

• AC power monitoring systems
• Industrial equipment current sensing
• Electrical distribution panel metering

Procurement Notes

Verify the specific ordering suffix against official CR Magnetics documentation to ensure correct terminal type and insulation class. Confirm that the required frequency range aligns with the 50Hz to 400Hz specification. Check for any regional compliance certifications such as UL or CE if required for your installation environment. Ensure the mounting hardware matches the chassis mount requirements.

Selection Notes

Select this component when a non-invasive solution is required for currents up to 800A. The 800:5 ratio is standard for interfacing with typical metering or control inputs. Consider the 2.5-inch ID to ensure compatibility with the primary conductor size. Verify that the operating frequency falls within the specified 50Hz to 400Hz band for accurate signal transformation.
