TWCT-T-D110 1000/5A VA 10 CL 0.5

Overview

The Selec Controls TWCT-T-D110 is a tape wound current transformer designed for AC electrical systems operating at 50Hz or 60Hz. It features a non-invasive solid core construction with an inner diameter of 110mm, allowing for free-hanging in-line mounting. The unit provides a current ratio of 1000:5A and supports a rated burden of 10VA. It achieves a class of accuracy of 0.5, complying with IEC 61869-2 standards. The thermal nominal continuous rating is 120% of the rated primary current.

Feature Summary

• Tape wound construction for reliable current sensing
• Non-invasive solid core design for easy installation
• Terminal output configuration for direct connection

Applications

• Current sensing in AC electrical distribution systems
• Metering applications requiring Class 0.5 accuracy
• Protection relay circuits in industrial power networks

Procurement Notes

Verify that the specific part number matches the required current ratio, burden, and accuracy class. Confirm the inner diameter fits the conductor size. Ensure compliance with local safety regulations and IEC standards before deployment.

Selection Notes

Select this model when a 1000A primary current and 110mm aperture are required. Choose based on the need for high accuracy (Class 0.5) and a 10VA burden capacity. Ensure the system frequency aligns with 50Hz or 60Hz operation requirements.

Part Context

This component belongs to the TWCT series of tape wound current transformers from Selec Controls. The series offers various primary ratings from 30A to 1600A and multiple accuracy classes. The D110 designation indicates the specific 110mm inner diameter variant within this product line.

Replacement Considerations

Direct substitutes include other Selec TWCT models with matching 1000/5A ratios and 110mm diameters. Verify compatibility with existing mounting hardware and terminal connections before replacement.
