MFO402005A

Current Sense Transformers Overview

The Omega MFO402005A is an AC current transformer designed for low-voltage applications, specifically intended for use with ammeters and wattmeters. It features a 200/5 A transformation ratio and a 5 VA burden rating. The device includes a 41.5 mm window aperture to accommodate primary conductors. This component belongs to the MFO series and is constructed as a single unit for integration into electrical measurement systems.

Current Sense Transformers Feature Summary

• Designed for accurate AC current sensing in low-voltage environments
• Compatible with standard ammeter and wattmeter inputs
• Provides isolated secondary output for safe measurement

Current Sense Transformers Applications

• Integration with panel-mounted ammeters
• Connection to low-voltage wattmeters
• Electrical monitoring circuits requiring 200 A primary current sensing

Current Sense Transformers Procurement Notes

Verify that the required primary current does not exceed 200 A and that the connected meter burden is within the 5 VA limit. Confirm the window size of 41.5 mm matches the conductor diameter. Ensure the application voltage remains within low-voltage classifications specified by the manufacturer. Check for CE compliance requirements if operating in regulated regions.

Current Sense Transformers Selection Notes

Select this model when a 200/5 A ratio is required for low-voltage AC measurements. Consider the 41.5 mm window dimension for busbar or cable fitment. Evaluate the 5 VA rating against the total burden of connected instruments. Compare against other MFO series variants if different ratios or window sizes are needed.

Current Sense Transformers Part Context

This component is part of the Omega MFO series of AC current transformers. These devices are engineered for industrial and commercial electrical monitoring. The series provides standardized ratios and mounting configurations for reliable integration into power distribution panels and control systems.

Current Sense Transformers Replacement Considerations

Consult official Omega Engineering documentation for direct substitutes. Verify that any replacement maintains the 200/5 A ratio, 5 VA rating, and 41.5 mm window dimensions. Cross-reference part numbers only through authorized manufacturer channels.
