CBCT-70-1

Current Sense Transformers Overview

The CBCT-70-1 is a closed toroidal current sense transformer manufactured by Altech Corporation. It features a chassis mount design with a 70mm inner diameter suitable for busbar applications. The device provides a high isolation voltage and maintains a precise 1000:1 turns ratio for accurate current monitoring. Rated for a maximum primary current of 30 A, it is engineered for industrial automation environments requiring reliable signal conversion from high-current lines to low-level sensing inputs.

Current Sense Transformers Feature Summary

• Closed toroidal geometry designed for direct mounting on rectangular or round busbars
• High accuracy 1000:1 turns ratio ensures faithful current signal reproduction
• Robust chassis mount construction supports secure installation in control panels

Current Sense Transformers Applications

• Industrial motor drive current feedback loops
• Power supply overcurrent protection circuits
• Automated machinery energy monitoring systems

Current Sense Transformers Procurement Notes

Verify the specific manufacturing date code upon receipt to ensure compliance with current RoHS3 standards. Confirm that the physical dimensions of the target busbar fall within the 70mm aperture tolerance before finalizing the order. Ensure that the mounting hardware provided is compatible with the enclosure panel thickness to maintain structural integrity during operation.

Current Sense Transformers Selection Notes

Select this component when a non-invasive current measurement solution is required for busbars up to 30 A. The 1000:1 ratio makes it suitable for driving standard analog-to-digital converters or operational amplifier circuits. Consider the physical space constraints of the control cabinet to accommodate the external toroid profile and necessary wiring clearance.

Current Sense Transformers Part Context

This model belongs to Altech's CBCT series of current transformers, which are widely used in industrial automation. The series offers various aperture sizes to match different busbar dimensions while maintaining consistent electrical performance characteristics across the product line for standardized system integration.

Current Sense Transformers Replacement Considerations

No public substitute part numbers are documented. Direct replacement requires matching the 70mm aperture size and 1000:1 ratio to ensure circuit compatibility.
