Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with system requirements. Confirm that the 40 A rating and 2500:1 ratio align with the intended application's electrical parameters. Check for any specific handling instructions regarding the wire leads and solid core structure during installation.

Selection Notes

Select this component when a high-isolation current transformer with wire leads is required for currents up to 40 A. Ensure the operating frequency falls within the 20 Hz to 1 kHz range. Consider the free-hanging in-line form factor for space-constrained or custom wiring layouts where traditional PCB mount transformers are unsuitable.

Part Context

This model belongs to the CR Magnetics current sense transformer family, which specializes in precision magnetic components for power electronics. The series is known for robust performance in industrial environments, offering reliable current feedback for control loops and protection circuits in various power conversion applications.

Replacement Considerations

When substituting, verify that the replacement part matches the 40 A rating, 2500:1 ratio, and 20 Hz–1 kHz frequency range. Ensure the new component supports wire lead termination and fits the physical constraints of the free-hanging in-line mounting style.
