Procurement Notes
Verify the specific part number TWCT-T-D55 200/5A VA 5 CL 1 against official Selec Controls documentation to ensure correct primary ratio and accuracy class. Confirm that the 55mm inner diameter fits the conductor size required for your installation. Check compliance with IEC 61869-2 standards if mandated by your project specifications.
Selection Notes
Select this model when a 200A primary to 5A secondary transformation is required with Class 1 accuracy. Ensure the application supports free hanging in-line mounting and utilizes terminal outputs. Verify that the 5VA rated burden matches the connected load impedance requirements for accurate performance within the 50Hz to 60Hz frequency range.
Part Context
This component belongs to the TWCT series of tape wound current transformers from Selec Controls. The series offers various primary current ratings ranging from 30A to 1600A, all sharing common design characteristics such as terminal outputs and compatibility with standard industrial control environments.
Replacement Considerations
Direct substitutes include other Selec models with identical electrical parameters, such as the TWCT-T-D55 250/5A VA 5 CL 1, provided the primary current rating difference is acceptable for the specific circuit application.
