CT-0150-F10

Overview

The Littelfuse CT-0150-F10 is a foot-mounted current transformer designed for use in 24VAC control circuits. It features a 150:5 current ratio and a 1-inch (25.4mm) sensor hole window. This component integrates delay-on-make and delay-on-break time delays into a single unit, allowing for the sequencing of multiple loads or controlled operation of identical loads.

Feature Summary

• Integrates delay-on-make and delay-on-break time delays within a single unit
• Foot-mounted design for secure installation in control panels
• Supports sequential load management for heating and cooling systems

Applications

• Control circuits for forced air heating equipment
• Control circuits for air conditioning units
• Fan delay control in HVAC systems
• Sequencing of electric heating elements

Procurement Notes

Verify that the specific part number CT-0150-F10 matches the required 150:5 ratio and 1-inch window size for your application. Confirm compatibility with 24VAC control circuit voltage ratings. Ensure the footed mounting style aligns with your panel layout requirements before finalizing procurement.

Selection Notes

Select this component when sequential timing control is required for multiple loads in HVAC applications. The integrated dual-delay functionality eliminates the need for separate timers. Ensure the primary current rating supports up to 150A and the secondary output matches standard 5A metering or control inputs.

Part Context

This device belongs to the Littelfuse CT Series of current transformers. These components are engineered specifically for industrial and commercial control applications where precise timing and current sensing are necessary. The series combines measurement capabilities with time-delay logic to simplify system design.
