7020-01046-0

Current Sense Transformers Overview

The Murata Power Solutions 7020-01046-0 is a commercial-grade, free-hanging in-line current transformer designed for AC current sensing applications. It features a solid-core construction with a 2000:5A turns ratio and a 15VA burden rating. The device provides an isolated output suitable for interfacing with associated signal conditioning circuits. Key physical dimensions include an outer diameter of 28.70mm (1.130 inches) and a seated height of 114.30mm (4.500 inches). It supports a maximum primary current of 5A AC.

Current Sense Transformers Feature Summary

• Provides electrical isolation between the primary circuit and secondary sensing load
• Features a free-hanging in-line form factor for direct wire integration
• Delivers a standardized 5A secondary output proportional to the primary current

Current Sense Transformers Applications

• AC current monitoring in power distribution systems
• Integration with signal conditioning modules such as DATEL ACA5
• Commercial grade industrial equipment current sensing

Current Sense Transformers Procurement Notes

Verify that the specific application requires a 2000:5A ratio and 15VA burden capacity. Confirm compatibility with the intended secondary load impedance to ensure accurate current transformation. Ensure the physical clearance accommodates the 114.30mm seated height and 28.70mm diameter. Check for UL and CSA recognition requirements if mandated by local safety standards for the end product.

Current Sense Transformers Selection Notes

Select this component when a through-hole, in-line current transformer is required rather than a split-core or PCB-mount variant. The 2000:5A ratio is optimal for stepping down higher primary currents to a manageable 5A secondary level. Consider the solid-core design constraints, which require the primary conductor to pass through the center aperture during installation. Evaluate thermal performance within the specified commercial operating range.

Current Sense Transformers Part Context

This part belongs to the 7020 series of commercial-grade AC current transformers from Murata Power Solutions. These devices are typically recognized by UL and CSA standards. The series includes various ratios and configurations, with the 7020-01046-0 specifically designated for in-line solid-core applications providing isolated current feedback.

Current Sense Transformers Replacement Considerations
