CR7SFT-201

Overview

The CR7SFT-201 is a commercial class AC current transformer manufactured by CR Magnetics Inc. It features a non-invasive solid core design with a 2.5-inch inner diameter, suitable for chassis mounting. The device operates within a frequency range of 50Hz to 400Hz. It supports an input current rating of 200A and provides an output current ratio of 200:5, delivering up to 5A. The unit includes two terminals compatible with #8-32 hardware for secure electrical connections.

Feature Summary

• Non-invasive solid core construction for safe current monitoring
• Commercial grade performance for standard industrial applications
• Chassis mount configuration with integrated terminal access

Applications

• Industrial automation systems requiring current sensing
• Electrical panel monitoring and protection circuits
• Power distribution equipment for load measurement

Procurement Notes

Verify the specific model suffix and terminal configuration against project requirements before ordering. Confirm that the 2.5-inch inner diameter accommodates the target conductor size. Ensure the operating frequency range of 50Hz to 400Hz aligns with the system's power supply characteristics. Cross-reference the 200:5 ratio with downstream metering or control device specifications to guarantee accurate signal transmission.

Selection Notes

Select this component when a robust, commercial-grade solution is needed for high-current monitoring up to 200A. The solid core design eliminates the need for circuit interruption during installation. Consider the chassis mounting style for fixed installations where space allows for the specified inner diameter. This model is appropriate for general-purpose industrial environments rather than specialized hazardous locations.

Part Context

This part belongs to the CR Magnetics current sense transformer series, designed for reliable AC current measurement. It serves as a critical interface between high-power circuits and low-power monitoring instrumentation. The product line emphasizes durability and ease of integration into existing electrical infrastructure through standardized mounting and connection methods.

Replacement Considerations

The 1411-2SFT-201 is a documented alternative from P-Team Technology Inc. with similar 200A/5A ratios. Verify dimensional compatibility, particularly the inner diameter and mounting footprint, before substitution. Ensure the replacement meets the same frequency and accuracy requirements for the specific application.
