CT-0200-F10

Overview

The Littelfuse CT-0200-F10 is a non-invasive, single-conductor current transformer designed for industrial quality protection applications. It features a 200:5 current ratio and accommodates a conductor with a 1-inch (25.4 mm) window size. The unit supports a nominal current rating of 200 A and utilizes a footed mounting style with terminal block termination. This component is RoHS3 compliant and operates as a passive sensing device without requiring external power.

Feature Summary

• Foot-mounted design for secure installation on standard surfaces
• Non-invasive single-conductor sensing capability
• Terminal block termination for straightforward electrical connection

Applications

• Industrial quality protection systems
• Current monitoring in electrical distribution panels
• Metering applications requiring 200:5 signal output

Procurement Notes

Verify the specific manufacturing source, as Littelfuse acquired Hamlin components; ensure the part number matches the exact 200:5 ratio and 1-inch window specification. Confirm RoHS3 compliance status if environmental regulations apply to your project. Check that the terminal block termination style aligns with your wiring infrastructure requirements before finalizing procurement.

Selection Notes

Select this model when a 200:5 transformation ratio is required for conductors up to 200 A passing through a 1-inch aperture. The footed style is appropriate for fixed installations where space allows for base mounting. Ensure the application does not require invasive clamping or split-core access, as this is a solid-window design.

Part Context

This component belongs to the Littelfuse CT Series of current transformers, which are engineered for reliable current sensing in industrial environments. The series offers various ratios and window sizes to accommodate different conductor diameters and current levels. The CT-0200-F10 specifically addresses needs for moderate current ranges with a standardized 1-inch opening.

Replacement Considerations

Cross-reference other models within the CT Series, such as CT-0150-F10 or CT-0250-F10, if the current rating or ratio requires adjustment. Verify that any substitute maintains the same 1-inch window dimension and footed mounting configuration to ensure mechanical compatibility.
