Overview
The Littelfuse CT-0100-F10 is a footed current transformer from the CT Series, designed for industrial applications. It features a 1-inch window and provides a current ratio of 100:5. The device incorporates both delay-on-make and delay-on-break time delay functions within a single unit. This component is suitable for controlling fan delays in heating and cooling equipment. It operates at voltages ranging from 200 to 480V and utilizes a SPDT configuration.
Feature Summary
- Combines delay-on-make and delay-on-break time delay functions into one unit
- Designed for controlling fan delays in heating and cooling equipment
- Features a 1-inch window with footed mounting style
Applications
- Fan delay control in heating equipment
- Fan delay control in cooling equipment
- Industrial current sensing applications
Procurement Notes
Verify the specific application requirements against the official datasheet before procurement. Confirm that the 100:5 current ratio and 1-inch window dimensions match the system design. Ensure compatibility with the intended voltage range of 200-480V. Check for any regional availability restrictions as indicated by the manufacturer. Always refer to the latest product documentation for accurate specifications.
Selection Notes
Select this component when a combined time delay function is required for fan control in HVAC systems. The 100:5 ratio suits applications requiring precise current monitoring. Consider the footed model for stable mounting. Evaluate the 1-inch window size to ensure it accommodates the conductor. Verify that the SPDT configuration meets the circuit switching needs.
Part Context
The CT-0100-F10 belongs to the CT Series of current transformers manufactured by Littelfuse Inc. This series is characterized by its ability to integrate time delay functionalities directly into the current sensing device. The part is specifically engineered for industrial environments, providing reliable performance in heating and cooling applications where fan delay control is critical.
Replacement Considerations
Consult the official Littelfuse documentation for direct substitutes. The CT-0050-F10 offers a 50:5 ratio, while the CT-0150-F10 provides a 150:5 ratio, both sharing the same 1-inch window and footed design. Ensure any replacement maintains the required current ratio and time delay characteristics.
