CT-0800-F30

Overview

The Littelfuse CT-0800-F30 is a solid core current sense transformer designed for industrial applications. It features an 800:5 turns ratio and a 3-inch diameter window to accommodate primary conductors. The device operates at a maximum voltage of 600V AC and supports secondary currents ranging from 2A to 20A. Constructed with a footed design, it facilitates secure mounting in control circuits operating at 24VAC.

Feature Summary

• Solid core construction with a large 3-inch window for easy conductor installation
• Footed design ensures stable mechanical mounting within electrical enclosures
• High isolation rating suitable for 600V AC industrial power systems

Applications

• Industrial load sequencing for electric heating elements
• Control circuit monitoring in forced air heating systems
• Current sensing in air conditioning unit management

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the required insulation class and mounting style match the intended enclosure requirements. Cross-reference the datasheet for precise dimensional tolerances before integration into the final assembly design.

Selection Notes

Select this component when a high-current primary measurement is required without breaking the main circuit. The 800:5 ratio provides accurate scaling for standard industrial control inputs. Ensure the physical window size accommodates the primary busbar or cable diameter used in the specific application environment.

Part Context

This model belongs to the Littelfuse CT Series of current transformers. These devices are engineered for general-purpose current sensing in demanding environments. The series offers various ratios and window sizes to suit different power distribution needs while maintaining consistent performance standards across the product line.

Replacement Considerations

Direct substitutes must match the 800:5 ratio, 3-inch window diameter, and 600V rating. Verify that alternative components support the same footed mounting configuration and 24VAC control circuit operation to maintain system compatibility.
