CT1025

Overview

The CT1025 is a current sense transformer manufactured by Amgis, LLC, designed for through-hole mounting. It features a non-invasive solid core construction and operates at 50/60Hz frequencies. The device has a current rating of 25 A with a 1000:1 current ratio. Its secondary DC resistance is 48 Ohms. The component supports primary to secondary insulation and is RoHS compliant.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• Primary to secondary electrical insulation for safety isolation
• Through-hole mounting configuration for PCB integration

Applications

• Electrical current monitoring in power systems
• Current sensing in AC power distribution networks
• Protection circuitry requiring galvanic isolation

Procurement Notes

Verify the specific part number suffix against official Amgis documentation to confirm exact specifications. Ensure compatibility with 50/60Hz operating environments. Confirm through-hole footprint dimensions match target PCB layout requirements before procurement.

Selection Notes

Select this component when a 25 A current rating and 1000:1 transformation ratio are required. Consider the 48 Ohm secondary resistance for signal conditioning circuit design. Verify that the non-invasive solid core geometry accommodates the primary conductor size in the application.

Part Context

The CT1025 belongs to the CT Series of current sense transformers from Amgis, LLC. This series covers current ratings from 5 A to 200 A. These components are engineered for monitoring electrical currents with high isolation standards and wide temperature operating ranges.

Replacement Considerations

Consult official Amgis cross-reference lists for verified substitutes. Generic current transformers may not match the specific 1000:1 ratio or 48 Ohm impedance characteristics.
