CBCT-310-1

Current Sense Transformers Overview

The Altech CBCT-310-1 is a closed toroid core balance current transformer designed for earth fault protective relays. It features an inner diameter of 310 mm and a turns ratio of 1,000:1. The device supports an operating current range from 10 mA to 30 A. This component facilitates accurate current sensing in electrical distribution systems.

Current Sense Transformers Feature Summary

• Closed toroid design for secure cable installation
• High turns ratio for precise earth fault detection
• Wide operating current range for versatile applications

Current Sense Transformers Applications

• Power transmission and distribution networks
• Electrical equipment protection systems
• Industrial machinery safety circuits
• Renewable energy system monitoring

Current Sense Transformers Procurement Notes

Verify the specific application requirements against the 1,000:1 turns ratio and 310 mm inner diameter before ordering. Confirm compatibility with existing earth fault protective relays regarding the 10 mA to 30 A operating current range. Ensure that the closed toroid form factor fits the physical constraints of the installation site. Cross-reference the manufacturer part number to avoid confusion with similar open-core variants.

Current Sense Transformers Selection Notes

Select this model when a high-ratio current transformer is required for ground fault monitoring. The 310 mm aperture accommodates larger cables or busbars commonly found in main distribution panels. Consider the 1,000:1 ratio for sensitive detection needs where low-level leakage currents must be identified reliably. Evaluate the closed design benefits for environments where rapid installation without cable disconnection is necessary.
