TWCT-T-D120 1200 /5A VA 10 CL 0.5

Overview

The TWCT-T-D120 1200/5A VA 10 CL 0.5 is a tape wound current transformer manufactured by Selec Controls USA Inc. It features a solid core design with an inner diameter of 120mm, supporting primary currents up to 1600A and secondary outputs of 5A. The unit operates within a frequency range of 50Hz to 60Hz and maintains a rated burden of 10VA with an accuracy class of 0.5. Thermal nominal continuous rating is defined as 120% of the rated current.

Feature Summary

• Non-invasive solid core construction for in-line mounting
• Tape wound technology ensuring high precision measurement
• Terminal output configuration for direct connection

Applications

• Industrial power monitoring systems
• Electrical metering infrastructure
• Current sensing applications in switchgear

Procurement Notes

Verify that the specific part number matches the required primary current ratio and accuracy class for your application. Confirm the inner diameter specification aligns with the conductor size being monitored. Ensure the rated burden capability meets the requirements of the connected measuring instrument or relay. Check for any specific ordering suffixes that may alter terminal configurations or packaging details.

Selection Notes

Select this component when a non-invasive solution is required for high-current measurements up to 1200A. The 120mm inner diameter accommodates larger busbars or cables without requiring circuit interruption. Consider the 10VA burden capacity to ensure compatibility with downstream devices. Verify that the 50-60Hz frequency range matches the system operation.

Part Context

This model belongs to the TWCT series of tape wound current transformers from Selec Controls. The series offers various inner diameters ranging from 35mm to 120mm and supports primary ratings from 30A to 1600A. These components are designed for accurate current transformation in electrical distribution networks.

Replacement Considerations

Direct substitutes include other models within the TWCT series such as the TWCT-T-D120 1600/5A VA 10 CL 0.5 if higher current capacity is needed. Cross-reference technical specifications including accuracy class and burden before substitution.
