TWCT-T-D120 1600 /5A VA 10 CL 0.5

Overview

The Selec Controls TWCT-T-D120 is a non-invasive solid core current transformer with a primary rating of 1600A and secondary output of 5A. It features a 120mm inner diameter, rated burden of 10VA, and accuracy class 0.5. Designed for 50Hz to 60Hz AC systems, it supports thermal nominal continuous operation at 120% of In. The unit utilizes terminal output and complies with IEC 61869-2 standards.

Feature Summary

• Non-invasive solid core design for easy installation around conductors
• High precision accuracy class 0.5 for reliable metering applications
• Tape wound construction ensuring stable performance under thermal loads

Applications

• AC electrical system current sensing
• Industrial power monitoring
• Energy metering installations

Procurement Notes

Verify the specific suffix codes against official Selec documentation to confirm exact physical dimensions and terminal configuration. Ensure the application frequency matches the 50Hz or 60Hz specification. Confirm that the required accuracy class 0.5 meets the project's metrological requirements before finalizing the order.

Selection Notes

Select this model when a 1600A primary current capacity is required with a 120mm aperture. The 10VA burden rating must align with the connected load impedance. Consider the tape-wound construction for applications requiring robust thermal stability up to 120% of nominal current without saturation.

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 inner diameters. The D120 designation specifically indicates the 120mm inner diameter variant within this product line.

Replacement Considerations

Cross-reference part numbers such as TWCT-T-D120-1600/5A-VA10-CL0.5 for identical specifications. Verify compatibility with existing mounting structures due to the fixed 120mm inner diameter constraint.
