Procurement Notes
Verify the specific ordering code matches the required parameters, such as the 500/5A ratio and 5VA burden. Confirm that the 65mm aperture fits the conductor size. Ensure the accuracy class 1 meets the application requirements. Check compliance with IEC 61869-2 standards. Validate the manufacturer source as Selec Controls USA Inc.
Selection Notes
Select this model when a 500/5A transformation ratio is required for metering or protection. The 65mm aperture accommodates conductors up to that diameter. Choose based on the need for Class 1 accuracy and 5VA burden capacity. Consider the terminal output style for wiring compatibility. Verify the 720V maximum system voltage rating for safety.
Part Context
This component belongs to the TWCT series of tape wound current transformers from Selec. The series offers various ratios from 30A to 1600A and different accuracy classes. The D65 designation indicates the 65mm wire aperture size. These transformers are designed for reliable performance in industrial environments.
Replacement Considerations
Cross-reference with other Selec models in the TWCT series for similar aperture and ratio requirements. Verify that any substitute maintains the 5VA burden and Class 1 accuracy specifications. Ensure the replacement supports the same terminal output and mounting style.
