Overview
The TWCT-T-D110 is a tape wound current transformer manufactured by Selec Controls USA Inc., designed for AC electrical systems operating at 50Hz or 60Hz. It features a primary current rating of 800A and a secondary output of 5A. The unit has an inner diameter of 110mm, a rated burden of 10VA, and an accuracy class of 0.5. It complies with IEC 61869-2 standards and supports thermal nominal continuous operation at 120% of In.
Feature Summary
- Tape wound construction for reliable current sensing in AC systems
- Terminal output configuration for direct connection
- High accuracy class 0.5 performance
- Free hanging in-line mounting design
Applications
- Current sensing in AC electrical distribution systems
- Metering applications requiring Class 0.5 accuracy
- Industrial power monitoring setups
Procurement Notes
Verify the exact part number suffixes against official Selec documentation to ensure correct primary current, burden, and accuracy class specifications. Confirm that the 110mm inner diameter matches the conductor size required for your installation. Cross-reference the IEC 61869-2 compliance status if specific regulatory adherence is mandatory for your project requirements.
Selection Notes
Select this model when a 800A primary current rating and 110mm aperture are required. Ensure the system operates within the 50Hz to 60Hz frequency range. Verify that the 10VA rated burden aligns with the connected metering or protection device load. Consider the terminal output type for wiring compatibility with existing control panels.
Part Context
This component belongs to the TWCT series of tape wound current transformers from Selec. The series offers various primary ratings from 30A to 1600A and multiple inner diameters including 35mm, 55mm, 65mm, 110mm, and 120mm. Accuracy classes range from 0.5 to 5, with burdens between 1.5VA and 10VA, providing flexible options for different sensing needs.
Replacement Considerations
Direct substitutes include other TWCT-T-D110 variants with identical 110mm diameter but different primary currents (e.g., 1000/5A) or accuracy classes. Ensure any replacement maintains the 10VA burden and 5A secondary output to preserve circuit compatibility.
