CR5SFT-501

Current Sense Transformers Overview

The CR5SFT-501 is a commercial class current sense transformer manufactured by CR Magnetics Inc. It features a 500:5 secondary ratio and supports input currents up to 500 A. The device operates within a frequency range of 50 Hz to 400 Hz and maintains 1% accuracy at 60 Hz. It utilizes a chassis mount configuration with a 1.56-inch window diameter. The unit measures 3.780 inches in length and 2.150 inches in width, with a maximum mounting height of 3.780 inches (96.00 mm).

Current Sense Transformers Feature Summary

• Chassis mount design for secure installation
• Commercial grade construction for general applications
• High current sensing capability up to 500 A

Current Sense Transformers Applications

• Industrial power monitoring systems
• Electrical distribution panels
• Motor control circuits

Current Sense Transformers Procurement Notes

Verify the specific secondary ratio and accuracy requirements against the application datasheet. Confirm that the chassis mount dimensions align with the available panel space. Ensure the operating frequency range covers the system's fundamental frequency. Check for UL recognition status if regulatory compliance is required for the end product.

Current Sense Transformers Selection Notes

Select this component when high-current AC measurement is required in a commercial setting. The 500:5 ratio suits applications where standard 5 A instrumentation inputs are used. Consider the physical size constraints due to the chassis mount style. Verify that the 1% accuracy at 60 Hz meets the precision needs of the monitoring circuit.

Current Sense Transformers Part Context

This part belongs to the CR5SFT series of current sense transformers from CR Magnetics Inc. The series offers various ratios for different current ranges while maintaining consistent physical dimensions and mounting styles. These components are designed for reliable performance in industrial environments requiring accurate current feedback.

Current Sense Transformers Replacement Considerations

Direct substitutes include other CR5SFT models with matching ratios, such as CR5SFT-201 or CR5SFT-101, provided the current rating differences are acceptable. Cross-brand replacements must match the 500:5 ratio, chassis mount form factor, and 1.56-inch window diameter.
