CT-0150-D10

Overview

The Littelfuse CT-0150-D10 is a non-invasive solid core current transformer designed for industrial applications. It features a donut-style construction with a 1-inch (25.4 mm) window to accommodate primary conductors. The unit operates at a voltage class of 600V and provides a standard current ratio of 150:5, converting primary current into a secondary output suitable for metering devices. It utilizes wire leads for connection and supports free-hanging in-line mounting. The component is RoHS compliant and lead-free, ensuring adherence to environmental standards while delivering reliable current sensing performance.

Feature Summary

• Donut style construction with a 1-inch sensor hole window
• Non-invasive solid core design for free-hanging installation
• Standard 150:5 current ratio for accurate sensing
• RoHS compliant and lead-free manufacturing

Applications

• Industrial current monitoring systems
• Electrical metering equipment
• Power distribution panels
• Three-phase voltage meter integration

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official documentation to ensure the correct configuration. Confirm that the required voltage class and current ratio match the system requirements. Check for any specific shipping restrictions or handling instructions provided by the supplier. Ensure compatibility with existing wiring methods using wire leads. Validate RoHS compliance status if required by project specifications.

Selection Notes

Select this model when a 150:5 ratio is required for primary currents up to 150A. The 1-inch window size dictates the maximum conductor diameter that can pass through the center. Consider the 600V rating for appropriate insulation levels in the application environment. The free-hanging mounting style allows for flexible installation without additional brackets. Ensure the secondary load does not exceed the transformer's burden capacity.

Part Context

This component belongs to the Littelfuse SymCom series of current transformers. It is categorized as a current sense transformer used for measuring alternating current in electrical circuits. The part number indicates the specific ratio and physical dimensions within the product line. It serves as a critical interface between high-current lines and low-current measurement instruments.

Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalent part numbers. Ensure replacement units maintain the same 150:5 ratio and 1-inch window dimension. Verify compatibility with existing mounting and wiring configurations. Do not assume functional interchangeability based solely on similar ratings.
