Procurement Notes
Verify the specific suffix codes against official Selec documentation to ensure exact match of burden and accuracy class ratings. Confirm physical dimensions and mounting requirements align with the target assembly specifications before finalizing procurement orders.
Selection Notes
Select this component when a 50:5 ratio and 5VA burden are required for 50-60Hz applications. Ensure the 35mm inner diameter accommodates the primary conductor size. Verify that accuracy class 5 meets the system's measurement tolerance requirements.
Part Context
This model belongs to the TWCT series of tape wound current transformers from Selec. It shares the D35 designation indicating a 35mm inner diameter with other variants in the family, differing primarily in current ratio, burden, and accuracy class specifications.
Replacement Considerations
Direct substitutes must match the 50:5 ratio, 5VA burden, and 35mm bore. Cross-reference part numbers like TWCT-T-D35-30/5A-VA1.5-CL5 only if burden and ratio adjustments are acceptable within the system design constraints.
