Procurement Notes
Verify the specific manufacturer part number against official TE Connectivity or Crompton documentation to ensure compatibility. Confirm that the required accuracy class and frequency range meet the target application's technical specifications before procurement.
Selection Notes
Select this component when a 400:5 current ratio and 10 VA burden capacity are required. Ensure the operating environment is indoor and the system voltage does not exceed 600 V. Verify that the conductor size fits within the 26.7 mm window diameter.
Part Context
This model belongs to the Series 2 line of current transformers from Crompton Instruments, now part of TE Connectivity. The series is engineered for general-purpose electrical metering and protection tasks, offering standardized dimensions and performance metrics for easy integration into existing switchgear and control panels.
Replacement Considerations
Consult official TE Connectivity substitution guides for verified equivalent models. Do not assume cross-compatibility with other series without confirming electrical parameters and physical dimensions.
