• Current measurement in variable frequency drives

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Procurement must rely on remaining stock or secondary market suppliers. Verify part authenticity carefully due to potential availability of obsolete inventory. Confirm compatibility with existing mounting brackets if required, as optional accessories may no longer be produced alongside the main unit.

Selection Notes

Select this model only for legacy systems requiring a 2500/5 ratio with specific dimensional constraints. Ensure the operating frequency falls within the 25-400 Hz range. Consider modern replacements if new installations are planned, as supply chain support for discontinued items is limited. Validate that the 600V insulation rating meets the specific circuit requirements.

Part Context

The CT-2500/5 belongs to the CT Series of current transformers from ATC Diversified Electronics. This series is designed for industrial applications requiring reliable current sensing. The specific model represents a high-capacity variant within the lineup, catering to heavy-duty power monitoring needs before its discontinuation status was implemented.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Users should consult manufacturer archives for equivalent series models or contact authorized distributors for legacy support options. Generic replacements may not match the specific dimensional or frequency specifications.
